Hi Luis!
I'm so happy to help you get ready for your magical Walt Disney World Resort vacation! We also have three little Mouseketeers in our family, so I know how important it is to have a good stroller with you!
Per the
Walt Disney World Resort Property Rules, Guests are welcome to bring strollers with them into the theme parks, provided they aren't larger than 31" (79 cm) in width and 52" (132 cm) in length. I looked up the dimensions of the UPPAbaby Vista and it looks like it falls well within the required size limits. I recommend that you add the PiggyBack attachment and a RumbleSeat, if you'll be using one, and measure the length and width of your stroller again to make sure you're still within the required size limitations. If it is, then you're welcome to bring it into the theme parks with you and it will be the perfect ride for your little ones!
Luis, be sure to take advantage of the
Baby Care Centers while you're visiting the theme parks because they are perfect for taking care of your little ones' needs. They are a nice quiet place to feed and change them, plus you can purchase any supplies for them that you need during your trip!
Come back to see us if you have additional questions as you continue planning. T-T-F-N, ta ta for now!
