Beautiful Island, Hot Stay

The island is beautiful! The stay at the hotel was okay, the staff were amazing, funny, and friendly. However a lot of items at the hotel needed repair it felt like. The hot tub jets didn’t work, but it was still nice and warm. The worst part was that the A/C in the room didn’t work it was so hot, they did offer us fans but it was terrible. We tried to keep the door open but bugs kept coming in. Again the staff were amazing, just for the price and the current conditions of the hotel it was not worth it. Once they get the A/C fixed and put some TLC into the pool area and decks of the rooms it would be worth it. They did have complementary snores and games!!

Inn was overpriced ($600/night) for what you get. Limited food options and expensive based on quality. Nowhere to pick up a quick sandwich or muffin or fruit or yogurt…The food service was VERY slow ( min of 1.5 hr every time). Our breakfast was cold and overcooked. After waiting, entree never arrived and they had run out. Hot tub was broken and staff had no idea when it would be fixed. Ac was overloaded and didn’t work on arrival. Website indicates yoga on Sundays but was not accurate. Inn is inland not directly on the water.

The property is beautiful and the staff is always pleasant and talkative. However, since checking out there was an extra charge added to my card of a little over $100. I reached out to the Cove and was asked to send an email providing proof. Three days passed and I called numerous times with no answer to my calls or email. During my stay I had issues where I was charged almost $600 but was told it was due to booking with a 3rd party (Expedia). While that issue was resolved before check out I was not informed of any other charges outside the resort fee for after check out.

The hotel is over priced for what it is. Pool wasn’t clean and peeling paint. The rooms were nice, balcony is shared which was ok. It was beginning of the season so no one really knew who was doing what. Drinks weren’t good but I think they are struggling to get help. There is no where to buy anything outside of candy, icecream and small alcohol section. Lunch by the pool was simple but nice.

Lacking in hospitality

After we walked up a hill to the Inn with our kids and all our stuff, we were told “sorry” for not picking us up and then made to wait an hour (including having to feed baby in lobby) while they tried to find our reservation (while blaming us for booking through hotels.com). Once checked in, the rest of our stay was fine.
Food from the restaurant at the hotel was very average - edible but would not recommend or return.

Beautiful But Over Priced

Very misleading
Thought that the hotel was near the water
Pictures that were shown made you think that the hotel was near the water but it was a walk over the hill, walk to the beaches were over the hill
Very secluded and very quite
Hotel is centered in the middle of an old army barracks
Food was very expensive and average for the price
A lot of walking
The ferry schedule is very limited in September unless you want to walk 15 to 20 minutes over the hill to the other Ferry stop
Over priced!!

Its sad to say because this place has so much potential but clearly under staffed. They have the desk boy working 4 jobs and there isnt a lot of communication with everyone working. The facilities are so amazing just hard that they are not all free due to the price of the room. Also, the cleaning service never came to freshen our room. It just felt like we constantly were st the front desk asking for things that typically are done at a 3 star hotel.

We had a great stay! And everyone was very nice! And it was Beautiful and peaceful!! The only thing I will say is if you have to leave early arrange transport to the ferry the night before because the front desk is not open early, And calling the number went straight to voice mail. Also, coffee in the morning was not easily accessible. Will definitely go back… and I will take extra keurig pods ☕️

The Inn itself is gorgeous on a lovely quiet island for some exploring. The rooms are large and well maintained, and the staff while inexperienced does their best to help and answer questions.

Our room was ready when we got there early, and they let us check-in a few hours ahead which was greatly appreciated.

The pool is nice (a little chilly) and the hot tub was boiling, and we enjoyed relaxing by the pool. The beaches are nice to visit from a short walk but don't expect sandy beaches here.

We walked around the island, even outside of the homeowner's association barrier and there is a nice gift shop where you can get ice cream, popsicles and some treats for ~1 a pop. Surprisingly reasonable for this island.

The main issue with the island is food as one might expect, so just keep you expectations on the lower end (unlike the higher side prices) and you won't be too disappointed. The hotel restaurant is OK - the pancakes were at least good - but the two island restaurants left a lot to be desired.

Would we return? I think if you are looking for a short getaway or are willing to go to portland for food, it can make an excellent relaxing trip.

Beautiful property. My only complaint was due to travel, we had to take the 9pm ferry. There was not anyone there to greet us as it had said in email. Nothing like getting dropped off on an island in the dark with your children and luggage with no idea where to go. Luckily, we saw someone that pointed us in the right direction.

Complete relaxation

Absolutely wonderful stay! From the moment we walked into the lobby with the friendliness of Reception, during the two nights we were there and when we left. Total relaxation next to the pool and on our balcony. Very nice and clean rooms with plenty of space. The recreation room was fun, great idea.

There are a couple downfalls. The Market was closed so you have to wait for the restaurant to open which isn’t convenient for a family on a budget, so plan to eat on the Mainland or pack food to bring over - there are plenty of tables in the lobby area. The bikes are not complementary which is a bummer - in my opinion the cost of the rooms should cover the use. But these factors we worked around.
All in all we really enjoyed our two days and would definitely come back.

A little uneven. People were nice enough. We were there just as season was ending so this was contributing. The room was very nice except apparently not a single hypoallergenic pillow in the complex. When we asked, we were given some nonsense about it being end of season and they were out. How do have 70 rooms and only feather/down pillows? This is not exactly an unusual allergy. The restaurant was not terrific. Eat on shore and then ferry in for the evening. READ EVERYTHING ON THEIR SITE BEFORE GOING. THEY EXPLAIN NOTHING.

This is a beautiful property. The rooms are stunning, very clean and comfy beds. This is a hotel in the woods on an island.Think “Dirty Dancing” resort with families, not a romantic, quiet retreat. First off, DO NOT RESERVE IN ADVANCE. It is hardly ever full and NO fun in the rain. You will be charged in full unless you cancel 2 weeks in advance. There are two major issues: 1. There is no information provided as to how/where/hours to do things…(like eat) other than a simple map in the lobby; and 2. They play CONSTANT banging music at the pool that echoes up onto your 2nd floor balcony. It’s incessant and mind-numbing. Want to turn on the fireplace in your room that you paid extra for? Figure it out…but…it’s a trick. THEY need to turn it in for you EVERY TIME you want to use it. Or…you can take the grate off and, as the front desk told me…try to figure it out on your own. Want food? Figure it out. No answer at the front desk or “restaurant” phone line. No info/hours/transportation info (both off site) etc. There was a line at the desk to ask questions, so we decided to walk. Guess what…no signs pointing you to where to go, and in the dark it’s a challenge. There are no signs/pamphlets and limited people available to assist you. All the staff is under the age of 25. There is also a strong scent they pump throughout which gets to be a bit much after a while. They need printed info in the rooms explaining the amenities and food, signage, and turn down the music and the scent.

The location of the facility is wonderful. The island setting is beautiful, and the lack of cars makes it even better. However, the staff is mostly international students, who are outgoing and friendly but who don't seem to be well-trained. They didn't know how to answer questions or provide basic services like adding dining charges to the hotel bill or providing luggage assistance at checkout. Also, there were no housekeeping services provided during our entire stay, which meant no trash removal (even though our room had a kitchen and trash contained food items), and no replenishing of coffee, shampoo, etc. The hotel could easily be a 5 star facility if some basic services were improved.

We had a great stay at the Inn at Diamond Cove. It started off a little rough as we couldn’t get anyone to answer the phone on the day of checkin. This made our transfer to the island a bit complicated. After several attempts we finally got someone and worked everything out.
We then discovered the main restaurant on the island was closed for the season so only the bar cafe was open. We learned the hotel was closing after our weekend there. The food was good but they had a hard time handling a gluten free guest. The smell in the upstairs hallway wreaked of a really strong perfume that was annoying. This is apparently pumped into the ventilation system. Otherwise we enjoyed the location, walking around the island, and the ambiance of the hotel. Would definitely come again in season, not the last weekend they’re open.

WE never saw the property so I cant speak of the stay. They refused my refund then agreed to refund some of it. but kept 580 for the first night. DO your research so it does not happen to you. Hotels.com did not state this at all. I reviewed my booking!!!

A Pleasant Stay.

Stayed there for three days. Lovely inn with a young, enthusiastic staff. Definitely a staff shortage, but that is an industry-wide problem. The inn hired college aged Eastern European personnel who were both pleasant and attentive. Limited activities at the resort and on the island, but that is not necessarily a bad thing. It gave my wife and I more time to read books and sip cocktails on the relaxing patio.

Nice, but go in with the right expectations

First of all, it wasn't clear to me when I booked that this property is located ON AN ISLAND. That completely changed the feel of our vacation. It was a unique experience and there were many nice aspects about staying on the island, but if you want to spend time in Portland, understand that you will be either paying for an expensive water taxi or tied to a ferry schedule. The hotel itself was very nice and the staff was lovely (even though I don't think we spoke to a single employee over the age of 25, which was interesting). However, the amenities are quite outdated and not what we pictured. The \"fitness center\" is filled with old equipment, the \"arcade\" has one functioning video game, the \"bowling alley\" is candlepin bowling where you have to set up the pins yourself, and the bike rentals are for no less than six hours at a time. Oh, and the fireplace in our room did not work. If you are aware of all this and still think it sounds like something you're interested in, you'll probably have a wonderful time. For us, while it didn't ruin our trip by any means, if we had to do it over again, we definitely would have picked a place right in Portland.

The staff was friendly and tried their very best. There was confusion, however, in directions for parking, arrival, and general workings of the hotel. As sweet as the Island is, as nice as the rooms are, many of the other amenities were substandard, the hotel is understaffed, and general confusion abounds.
