Hi Alycia!
I am thrilled to hear you will be visiting the Walt Disney World Resort so soon! How exciting! Soon you will be experiencing all of the magic in a Disney vacation with your little princesses. Love that!
Personally, I prefer to rent our stroller from an outside company, so we have it to use while waiting for transportation or when strolling around our resort. The double-mini type seems to be the most widely used because they fold up in a breeze and are still fairly narrow. Even though both of your daughters may not want to ride at the same time, I happen to like having the extra storage space the double has to offer. If you select the link below, Disney works with several stroller companies and lists them on their Stroller Rental Page. I have used Kingdom Strollers (www.kingdomstrollers.com) the last couple of times and they have been great!
If you would rather not worry about transporting it between the resort and parks, you can
rent strollers directly from Disney. Strollers are available at each of the four theme parks and at the Downtown Disney Area.
Have a wonderful vacation, Alycia!
Magical Wishes,
Lauren
