Grassy Key Bar Hotel

"Remodeled room, kitchen and bathroom was so nice and cute! Loved the free kayak, paddle boarding and bike rentals. Friendly check-in staff too! "

"We stayed at Kingsail 4 nights and were very pleased. It’s a very well maintained mote from the 1950’s (probably). Brings back memories of vacation as a child in the 70’s The beds were comfortable and the pool was clean. The location was perfect and breakfast was easy as there is a diner right across the street. When we return to Marathon we will definitely check for a vacancy here. If you’re looking for luxury look elsewhere but if a great low budget place is your desire?Don’t fret just book it. "

"I am so grateful we choose tranquility bay for our stay. First time to Florida keys and Marathon. Beautiful kept resort. We stayed in the 200S room. The workers were so amazing and nice. They smiled and so polite. Made the stay very nice and felt welcomed. The resort was so well kept. All pools were Beautiful. We had a heated pool right out if our room. With gorgeous landscaping. The private beach was so cool. For us it was a amazing stay, and hope to be back. Thank you so much."

"lovely property - disappointed that bottled water was offered in room for $5 when it costs less than $1 and is free at other hotels and why there is a charge for parking when it is plentiful "

"Room was perfect staff was the best I will recommend this resort"

"Nice having excursions there"
