Spacious Villas for the Whole Family
Make Memories in the Florida Keys
Set in the heart of the Florida Keys on the quieter shores of Marathon, Tranquility Bay Beachfront Resort offers a reunion experience that feels relaxed from the moment guests arrive. There’s no pressure to follow a rigid itinerary here. Some family members may spend the day by the water, others exploring the Keys, enjoying dinner together, or simply unwinding in the comfort of the villa. The beauty of staying together on property is the freedom for everyone to experience the trip differently, while always remaining connected.
Catering by Tranquility Bay
In addition to our on-site restaurants and bars, our team can happily cater private events throughout the resort, including ice-breakers with drink service and light bites to full buffets and family-style dinners.
