Paradise in the Keys
Reviewed 6 hours ago

A wonderful resort we have visited several times and never been disappointed in the facilities. Everything is run efficiently and the setting is off the charts. Highly recommend.and Marathon is such and eclectic place and close to Key West.

You Get What You Pay For
Reviewed 9 hours ago

Given the basic resort infrastructure and location, a property with luxe levels of service and amenities would charge twice as much. Yes: the housekeeping services are minimal (or, on one of our days, nonexistent), the linens and bedding are only adequate, the rooms are small and you have to fetch your own drink and food orders from the Tiki Bar. But, two hours from MIA, you get a genuine Keys experience in a pretty setting and well-maintained property, with white sand, blue Gulf and relaxed, friendly vibe. In response to reviews complaining of the cost at Butterfly and Tiki Bar, we'd point out that food & drink everywhere in the Keys are expensive, that the cottage kitchens are perfectly functional and well-equipped and that Publix and Winn-Dixie are minutes away -- as are some excellent casual dining alternatives (Castaway!). We enjoyed our stay. Highlight: Iguana sex! In the pool!

Not worth the price
Reviewed 12 hours ago

Nice property. Poor pillows, lumpy comforters, and bad shower head. Cleaning service was so late we canceled because we were already getting ready for dinner. We expected more for the price they charge.

Becoming Run Down
Reviewed 14 hours ago

Second stay here and it is getting worse. Broken dishwasher, bedroom drawers. Poor kitchen equipment. Random housekeeping in time & quality. Restaurants are average but very high cost. Broken sun loungers around crowded pool. Overpriced and run down now

Another paradise experience

We have been to Tranquility for the past four years and could not recommend it more highly. The ambience, the detail, the amenities were all superb. We love the iguanas that hang out nearby, and did laps in this, the largest pool in the Keys, every day.
