Hi there, Dilka! Thanks for bringing your question to the Disney Parks Moms Panel!
A stroller has been a necessity for my daughter each time we have visited the parks over the past five years. It's great for getting her quickly and safely around the parks and we love to store our ponchos, water bottles, and other necessities in the stroller as well. The Walt Disney World Resort does have
rules about what size strollers can be brought into the parks. Any stroller larger than 52" x 36" is prohibited from entering. It sounds like your stroller is within the regulations, so you shouldn't have a problem bringing it with you to the Most Magical Place on Earth.
Since you'll be traveling with a little one, I wanted to make sure you were aware of the
Baby Care Centers that are located in each park. These centers are really comfortable places to change diapers, feed children, and even rock them to sleep. They are also great places to simply take a breather away from the hustle and bustle of the parks.
I hope your visit to the Walt Disney World Resort is full of magic and memories!
