Hello, Stephanie, and welcome to planDisney!
As the Dad to two little ones, I definitely understand the importance of having the right stroller for a trip to the
Disneyland Resort. I'm happy to report that you should be absolutely fine with your selected stroller for your visit.
According to the
Disneyland Resort Stroller Rules, strollers larger than 31 inches in width and 52 inches in length are not permitted. Based on the dimensions you have provided, your stroller should pass through the size requirements as the assembled dimensions are 20.5 inches in width and 33.9 inches in length.
Since it sounds like you're visiting with little ones, I would highly recommend checking out the newly reimagined
Mickey's Toontown! There are all kinds of fun spaces for little ones to explore and numerous green spaces to relax and enjoy a picnic together. It's so much fun!
Thank you again for your question, Stephanie. I hope you have a fantastic visit to the Happiest Place on Earth. If you have any further questions or concerns, please don't hesitate to ask!
Have a Magical Day,
Greg
