On Royal Caribbean's Odyssey of the Seas, the bumper cars located in the SeaPlex are typically included in your cruise fare, meaning there is no additional charge to ride them. The SeaPlex is the largest indoor active space at sea, and the bumper cars are one of its headline complimentary attractions. However, it is important to note that sessions are scheduled at specific times throughout the day, which can be found in the Cruise Compass or the Royal Caribbean app. While the ride itself is free, popular times can result in long queues, so many savvy cruisers recommend arriving early or visiting during "port days" when the ship is less crowded. There are height and age requirements for drivers and passengers to ensure safety, but for most guests, it is a fun, "all-inclusive" way to enjoy the ship's high-tech entertainment offerings.
