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, you can generally bring a collapsible wagon on a cruise ship in 2026, but with strict usage limitations. Most major lines, including Carnival, Royal Caribbean, and Disney, allow them as long as they are fully collapsed and stored inside your stateroom when not in use. You cannot leave them in the hallways, as this violates maritime fire safety codes by blocking exit paths. Crucially, wagons are typically prohibited during embarkation and debarkation; you must carry your child or use a traditional stroller while boarding, as wagons are too bulky for the gangways and security lines. While on the ship, wagons are often restricted to the wide-open pool decks or specific kids' zones. Many parents find that a high-end "stroller wagon" (like a Veer or WonderFold) is accepted more readily than a "utility wagon" designed for the beach, but a compact umbrella stroller remains the recommended choice for navigating tight ship elevators and narrow corridor turns.
