The manager and the staff were amazing - we had an issue with the air conditioning in our room and they were very helpful and got us moved to another room. I wish there were some more options for food, and was disappointed that the bar was not staffed, but the inn was beautiful and the atmosphere relaxing!

Our anniversary was ruined at the Inn at Diamond Cove!! We called in advance to have a golf cart available to take us to the resort and when we arrived there was no shuttle. We called the hotel again and 20 minutes later it arrived. We traveled to this location to enjoy the jacuzzi and the jacuzzi heater was broken. We tried to go to sleep at 11 p.m. and a noise was thudding above our heads for an hour. Then, the noise started again at 5 a.m. I called the front desk 6 times from the room phone and there was no answer!!! So, in pajamas I walked down to the front desk and the woman started screeching at me that she got my calls... but their phone system didn't work and I should have known that... and the noise was not her problem! I told her that a guest should not have to stumble out of bed to talk to the front desk and I asked for a refund, to which she agreed, I then emailed the hotel manager and they refused to give me any compensation!! DO NOT STAY AT THIS HOTEL!! They take no responsibility for a terrible guest experience and they STINK!!!!!

Great hotel and lovely experience

Hotel was amazing, as were the restaurants and facilities. Very quaint, yet luxurious. They weren’t fully staffed yet, but they helped us any way we asked them to. Would definitely do it again.
