Hello Heather and welcome to the Disney Parks Moms Panel!
Twins! Twice the love, twice the fun! With a pair of one-year-old children, you will undoubtedly need access to a stroller.
Walt Disney World Resort recently
adapted their size restrictions for strollers. At this time, strollers must be 31" (79cm) wide and 52" (132cm) long or smaller. So, if your doubles stroller fits these dimensions, it should work just fine. If you find that your stroller is too large, I recommend considering one of
Disney's featured providers. These private rental companies will have strollers that conform to Disney's rules and will deliver the stroller directly to your resort for use during your entire trip.
I hope this helps with your planning! If you have more questions, come on back to the Disney Parks Moms Panel.
See ya real soon,
Anne
