Hey there, hi there, Claire! Welcome and thank you for your question.
Believe me when I tell you that I know there are a lot of moving and fluid parts to planning a
Walt Disney World vacation with little ones. Since my oldest grandson, who is now three, was an infant, we've been traveling with our grandkids a few times a year. Now that there are three under the age of four, I feel like nothing short of a circus train will help me wrangle all of their gear.
Unfortunately, even if you don't use it as a wagon, wagon strollers are prohibited according to the
park rules. The dimensions of the wagon wouldn't matter in this case, as wagons of any kind, including stroller wagons, are not permitted.
If it helps in any way, you can
rent a stroller at each of the theme parks. A single stroller is $15 per day, a double stroller is $31, but you can save if you prepay for multiple days.
I know this doesn't help if you have sleepy kids and all of their stuff to get back to your room at the end of the day. In that case, I recommend ScooterBug. They are a rental company not owned by Disney, but they are a Disney Featured Provider. They can drop the stroller off at bell services on the day of your arrival if you are staying at a
Disney Resorts Collection hotel, and they'll pick it up at the end of your stay.
I hope your visit is memorable in a most magical way, Claire.
Anna
