Top Grassy Key Hotel Reviews

Tranquility Bay Beachfront Hotel and Resort

Tranquility Bay Beachfront Hotel and Resort

8/10 Good
"Very good setting and good ideas/resort layout. When we arrived to check in, reception couldnt find our booking so took longer than expected. We asked about the sunset boat tour at reception but were told this was a third party on the beach who close at 5 so unable to get further info, would be good if the reception staff could provide more information or take bookings as they are advertising it. Food and drink at the hotel are expensive. General buildings and rooms could do with a bit of tidying up in places. Fire alarm panel in the building we were staying in was beeping with a fault most of the night so didnt manage to sleep too well."
