Aquabana Floating Lounge at Rhum Runner Aquapark — Family-Friendly Fun in Marathon, FL

On a sun-drenched shelf of the Florida Keys, the Aquabana floating lounge offers a low-key counterpoint to high-energy family play. Located off Marathon, Florida, the Aquabana 1HR gives parents a shaded perch while children launch themselves into the Rhum Runner Aquapark—an inflatable playground tethered to clear, warm Atlantic water. The setup is simple: a stable, buoyant platform with cushioned seating, canopy shade and room to stow coolers, surrounded by the turquoise shallows and waving seagrass beds that frame this part of the Keys. The experience balances relaxation and supervision. From your lounge you can watch kids climb slides, leap from ladders and scramble across obstacle modules, all within an easy swim back to the Aquabana. Lifeguards on duty and clear sightlines make this one of the most parent-friendly aquapark options in Marathon. For swimmers and snorkelers there’s an added bonus: the Keys’ nearshore reef structures and seagrass flats mean you may drift past small coral heads, parrotfish and juvenile snapper while the park hums behind you. What sets this offering apart is its local fit: this floating lounge is designed for the Keys’ unique marine environment—shallow, warm, and biologically active—plus it keeps the action mobile. The Aquabana’s canopy and deck arrangement create a comfortable base when sun and salt demand a break, and its proximity to shore means an easy return to Marathon for lunch or to replenish supplies. Marathon itself has long been a working Keys community where fishing, boatbuilding and reef conservation coexist; the nearby Florida Keys National Marine Sanctuary, designated in 1990, helps protect the coral and fisheries that make days like this possible. Practical details: the booking is typically sold by the hour, making it easy to slot into a morning of snorkeling or an afternoon boat cruise. Expect playful noise, splashes and sun—bring reef-safe sunscreen, water shoes for the ladder, and a dry bag for phones. This is not a remote, wilderness outing but a social, family-first slice of Keys boating culture: equal parts playground and porch on the water. If you want a day that mixes child-friendly thrills with true Florida Keys atmospherics—warm current, bright fish and a horizon of low islands—the Aquabana floating lounge is a strong, simple way to enjoy it. It’s a local-flavored alternative to crowded beaches and a practical basecamp for anyone exploring Marathon’s waters. Arrive at the marina 15 to 20 minutes early to check in, secure shade, and stow valuables in the dry storage. Most operators provide life vests for all ages; verify sizes for toddlers before booking. On calmer days the platform is almost motionless; when trade winds pick up the lounge rocks gently, which kids love but less steady swimmers might find tiring. No glass, please.
