About Isla Bella Beach Resort & Spa
Isla Bella Beach Resort & Spa sits on the coast in Marathon, Florida, a modern oceanfront property where every one of its 16 room categories faces the sea.
Couples can exchange vows outdoors with the water as a backdrop, with an indoor banquet hall available as a weather backup and for the elegant reception that follows.
In-house catering handles the food and drink, and a full resort buyout is available for couples who want the property to themselves.
Accommodation ranges from king rooms for two to two-bedroom oceanfront layouts and kitchenette suites sleeping up to six, so wedding parties and families can stay together on site.

My stay at this hotel was outstanding from start to finish. The property was beautiful, spotless, and very well maintained, but what truly made the experience exceptional was the staff.
