My boyfriend and I loved our stay at Tranquility Bay. We stayed right on the beach with a absolutly stunning view of the ocean. The rooms are so spacious and comfortable, with everything you need to feel at home. more

Tranquility Bay is one of the most beautiful places I have ever been. The location is perfect and the grounds are so gorgeous it's hard to believe it's real. The crisp white beach houses with the wide inviting porches are surrounded with tropical landscaping that is perfectly manicured and full of beautiful color.

Even though the weather was crummy (cloudy and windy, thanks Ida!), we... more

This is the second year in a row that we have stayed at Tranquility Bay Resort in unit 25. The view of the pool and meticulously kept grounds from the master bed room balcony is awesome.

Watching the sunset touch down while being serenaded at this bar was... more
