Ahoy there, Margaret! Welcome to planDisney! I'm glad that you found your way here with your question.
Because
Port Adventures are operated by independent tour operators, I cannot share whether or not their transportation will have onboard bathrooms. I have experienced Port Adventure transportation in
Cozumel, Mexico, with and without access to an onboard bathroom. For those that had a longer ride and no onboard bathroom was available, we stopped for a bathroom break.
While making your decision to book, make sure to check the "Know Before You Go" section of each Port Adventure on the
Disney Cruise Line website. Important information like accessibility, suggested attire and footwear, and any restrictions will be listed there. Port Adventures also vary in the minimum age of Guests participating in the activity, so if you are traveling with young ones, check the minimum age requirement, which will also be listed on each Port Adventure webpage.
Margaret, if you have any other questions, please sail back to
planDisney for answers.
Adventure is out there!
