Can anyone tell me what the rental strollers are like? Are they readily available? Do they recline for naps? I'm trying to decide how much to drag along on the airplane with 2 small kiddos, carseats, carryons... We'll bring one stroller for our 18-month-old, but our 3-year-old may or may not want to ride in a stroller. If the Disney ones are nice, maybe we won't need to drag 2 strollers through the airports. Thanks.
