Yes, in 2026, guests at Universal’s Cabana Bay Beach Resort are still permitted to bring their own inflatable tubes for use in the lazy river. This is a popular "pro-tip" because, unlike the water parks where tubes are provided, Cabana Bay requires guests to either purchase a tube at the "Tube Tracker" shop (usually costing between $10 and $20) or bring their own. The resort even provides complimentary air stations near the lazy river entrance to help you inflate your personal float. The only restriction is that the tube must be a standard, circular individual size; oversized novelty floats (like giant flamingos or multi-person rafts) are generally prohibited for safety and to prevent congestion in the winding river. Bringing your own tube not only saves money but also allows you to have a recognizable float in the often-crowded waters of the "Lazy River Courtyard."
