Axel's take: 7.9/10
A good Keys base for outdoor fun, but not guaranteed quiet. A simple, motel-style 3-star with a canal-side marina in Marathon, scored for what it is.
Coconut Cay is a simple, motel-style 3-star in Marathon, not a full-service beach resort. We'd pick it for a casual Keys trip: Tripadvisor and Expedia guests repeatedly praise clean, comfortable rooms and helpful staff, while the pool, loaner bikes, kayaks and paddleboards give it more appeal than a basic roadside motel. Canal-view rooms add outdoor seating by the water; kitchen suites suit longer stays.
The trade-offs are uneven sound insulation, highway noise in some rooms and resident roosters. Some guests also describe aging facilities and tight parking when busy. Booking.com lists a resort fee, and the hotel's current website explicitly excludes dockage from canal-view rooms—reserve boat slips separately rather than relying on older reviews. It's a good fit for independent explorers; we'd skip it for beachfront lounging, polished resort service or reliably quiet sleep.
