The room was very clean and grounds were shaded and very nice. The only issue I had was the size of our room, we stayed in the "Key Lime" room and it was so small you could barely move around. Perhaps the other rooms are bigger, but would not recommend this room if you like room to move. The hotel was within walking distance to almost everything and the hotel has bikes you can rent which was really nice. The daily happy hour was a nice touch, would suggest you add some beer rather than just wine to give guests a choice.

The room and grounds were fine. Lovely. No cheese in an omelet?? Dry toast, no butter?? If you can’t properly do breakfast, then don’t bother at all. So disappointing. We sent our daughter and son-in-law there for their honeymoon. It was supposed to be a special treat!

Really loved my stay at The Mermaid & Alligator! The property is beautiful and in a very convenient location — easy to walk or bike to just about everything. You can even rent bikes from the property. The hot breakfast every morning was amazing, and I appreciated having snacks and drinks available all day. The only small downside was that the room I was in, the Sun room, was pretty small, but the balcony was awesome and made up for it. Finally, the staff were all super kind and friendly. Overall, a great stay and I’d definitely come back!
