Remember that strollers or collapsible wagons (and practically everything else you bring aboard) need to be stored in your stateroom, and the largest storage space in most staterooms is the space under the bed, which is around 14 inches tall.

Yes, but with significant restrictions. Most major cruise lines (like Carnival, Royal Caribbean, and Disney) allow collapsible wagons, but they are typically prohibited from being used in public areas while the ship is in motion or during embarkation/debarkation. You are generally required to keep the wagon collapsed and stored inside your stateroom. This is a safety measure to prevent tripping hazards in narrow hallways and crowded elevators. Wagons are primarily allowed as a tool for transporting children or gear off the ship during port visits, especially for beach days. However, some lines have moved toward "stroller-only" policies, where a wagon is only permitted if it is officially classified as a "stroller wagon" with a push handle and safety harnesses. Always check your specific cruise line’s "Prohibited Items" list for 2026, as rules regarding large mobility devices and "oversized" strollers are becoming increasingly strict to manage limited deck and hallway space.
