Hello Daniela! Thank you for bringing your question to the Disney Parks Moms Panel. I'll be happy to help you be prepared for your visit tomorrow.
I completely understand that you would like to have the most suitable stroller option for both your toddler and infant. It sounds like you are already aware of the Walt Disney World Resort Property Rules, which state that strollers larger than 31" in width and 52" in length are prohibited. Unfortunately, if your stroller is 34" wide, I can't recommend that you bring it. I would hate to see your stroller turned away at security, your family sent back to your vehicle or hotel room to leave it, and then be without a stroller. That would definitely NOT be a magical way to begin your day!
I agree that while the rental strollers at the theme parks are great for small children of walking age, they are not necessarily suitable for infants. I have a few ideas that may help. I know when my children were young I had a small fleet of different sized strollers. Do you have another stroller you could bring that fits within the allowed dimensions? Even if it is a single stroller for your infant, you could then rent a park stroller or use an umbrella stroller for your toddler.
If that is not an option for you, I suggest renting a stroller from one of the many baby equipment rental agencies in the Orlando area. A quick internet search will turn up several. Some will deliver your choice of single or double stroller model to you at your Disney Resort Hotel, and others have pick-up and drop-off locations at Orlando International Airport. ScooterBug is the Disney Featured Provider. Guests who rent through ScooterBug do not need to be present for delivery or return of their rented equipment. The hotel staff will hold your rental for your arrival and take care of the return upon your departure. You can find information for ScooterBug on the
stroller rental page.
I'll also mention that when I looked up your stroller model online, I found a double stroller in a front-to-back configuration that measures 26.5" wide and 34" long. I recommend double-checking your stroller measurements. If these are the measurements of your stroller, then it does fit within the allowed dimensions.
Daniela, I hope you and your family have a wonderful visit. Please let us know if you have any additional questions. We are always happy to help.
