Hi, Jason! Welcome to planDisney. Thanks for visiting with your question as you prepare to set sail on your Disney Cruise.
You ask a great question, Jason. Collapsible wagons are permitted onboard, so my best guess is that you are able to bring yours with you as you embark on the ship with your water bottles inside. It sounds like a great use of space to me. If it helps you to travel a little lighter, you are also welcome to bring your own reusable water bottles onboard. There are water refill stations along the promenade deck for your convenience.
It won't be long before you sail away! If you need any last-minute packing suggestions, Disney Cruise Line offers a handy
packing checklist on their website. For the best experience while sailing, I encourage you to make sure you have the latest update of the
Disney Cruise Line Navigator app on your phone. The app will guide you through all of the activities and offerings throughout your cruise.
Have a fantastic voyage! I wish you many magical memories at sea.
