Yes, the bumper cars on Royal Caribbean are generally free of charge and included in the cost of your cruise fare. You will find this attraction in the "SeaPlex," a massive indoor multi-purpose sports and entertainment complex featured on Quantum-class ships (such as Quantum, Anthem, Ovation, Spectrum, and Odyssey of the Seas). Because the SeaPlex is a versatile space, the bumper cars are not available all day; the crew will host "sessions" that typically last 1 to 2 hours, during which they roll out the cars and set up the arena. While the ride itself is free, it is extremely popular, and the line can grow quite long, often with waits of 30 minutes or more. You do not need a reservation for standard sessions, but you must be at least 5 years old and 42 inches tall to ride with an adult, or 8 years old and 48 inches tall to drive solo. It is important to check the "Daily Planner" on the Royal Caribbean app to find the exact times for the bumper car sessions, as the arena is also used for basketball, roller skating, and soccer at other times during the day. As of 2026, Royal Caribbean continues to offer this as a "signature" free activity to maintain its reputation as the best cruise line for active families and multi-generational groups.
