We will be bringing at least one stroller (Maclaren Techno for our dd 9 months). Our other dd (turning 5 at the park) doesn't normally use a stroller, but I'm sure will need one at WDW. Maclarens or jogging strollers are about the only ones she'll fit in. We have a couple of options: 1) buy a second stroller for $99 (Maclaren Volo), or 2) put baby in backpack carrier and let older dd ride in Techno to and from the parks, then put the backpack in a locker, baby in the Techno, and rent a single stroller for older dd. Any thoughts?
