It depends on which Planet Hollywood property you are visiting. The Planet Hollywood Adult Scene and Beach Resort in Cancun (Costa Mujeres) does indeed feature a massive, winding Lazy River, which is a highlight of the resort's "Blue Lagoon" area. It even includes a "Grotto Bar" where you can grab a drink without leaving your tube. However, the Planet Hollywood Las Vegas on the Strip does not have a lazy river. Its "Pleasure Pool" deck features two large pools and a FlowRider surf simulator, but lacks the slow-moving river found at the tropical Caribbean location. For 2026 travelers, the Cancun resort is the go-to for a water-park-style experience, as it also includes a "Kids Splash Park" and multiple water slides, whereas the Las Vegas location focuses more on the high-energy "pool party" atmosphere with live DJs and VIP cabanas but strictly traditional pool footprints.
