Bonefish Bay Motel

Marathon

10/10 Excellent

This property is the cleanest resort style property and hotel I’ve stayed at in years. My wife and I typically travel utilizing our timeshare or Marriott but only needed a night so we could escape S Florida hustle and bustle. Found this quaint little hotel fir a excellent deal and boy was it tremendous. Remodeled units with big fridge and stylish furnishings. Did I say clean and sanitized by super hard working staff. Great big property with boat docks and launch and amazing fun full size...

We had a great spring break trip! It’s hard to find a hotel that will accommodate a family of 6 without having to get two rooms. The room was fresh and updated. Staff was super friendly. My kids loved the different options for pools. I recommend the mai tai from the bar!
