Hi Emily!
Thanks for stopping by the Disney Parks Moms Panel with your question. As the mother of 8 who have visited
Walt Disney World oodles of times, I certainly understand the need for your 5 year old to have a way to get around. Even though a stroller might seem too small for him in other situations, I always recommend that Guests either
rent a stroller or bring one with them for any children who are willing to ride in one. Wagons are among those things that are
not allowed inside the Parks so I would definitely go the stroller route if I were you. We have found the strollers we can rent from private companies (
Disney has Featured Providers they recommend) to vary in size and, requesting a larger style has often been the answer for an older child. Our kids have always been happy to have anything to ride in so I'm crossing my fingers your little one will be OK with it, too!
Please let us know if there is anything else we can to help you with your planning.
Have a magical day!
