Hi Jenelle,
Thank you for visiting the Disney Parks Moms Panel with your vacation planning question!
The official word from Walt Disney World Resort is that Keenz wagons (or any stroller wagons) are not allowed in the parks. Unfortunately, all wagons are on the
list of prohibited items for the parks. Wagons are pulled behind you, and they can cause a safety concern or tripping hazard for other guests. If you prefer not to bring your own stroller with you on vacation, you can always
rent a stroller in the parks. I personally have seen numerous families get turned around at the gates when they have tried to bring a Keenz (or other similar brand) wagon into the parks. This wastes valuable time from their vacation, since the wagon's are on the list of prohibited items, and they could have saved themselves the hassle if they read the policy ahead of time. It's great that you are taking the chance to double check before your vacation so that you can plan accordingly.
Wishing you magical memories,
Kaylene
