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.
