Yes, you can take a stroller on the various boat transportation options at Walt Disney World and Disneyland Paris, but the rules vary depending on the size and type of the vessel. For the large Ferries (like those connecting the TTC to Magic Kingdom) and the Friendship Boats (connecting EPCOT to Hollywood Studios), you can generally push the stroller right onto the deck without folding it, provided your child is awake and there is enough floor space. However, for the smaller "Water Taxis" and "Launch" boats (like those from the Grand Floridian or Polynesian), you must fold the stroller before boarding and stow it in the designated area to keep the aisles clear. In 2026, Disney strictly enforces the size limit for all strollers (31" wide and 52" long) and prohibits stroller wagons entirely. If you are using a "medical stroller" for a guest with a disability, it is treated as a wheelchair and can remain unfolded on any boat that is equipped with a ramp or lift. Always listen for the "all clear" from the boat captain before attempting to board with a large stroller to ensure the vessel is balanced correctly.
