to pp: one thing to think about is at end of night when kids are most tired, the park rental stroller has to be left inside the park. you have you walk to bus, boat or monorail with tired kids. plus you will have a walk of some sort back at resort. I would look at off site rental for these reasons. I know about having to fold stroller on buses can be a pain but so is just missing the bus back and waiting for next bus with no place for child to sit. been there and done that, never again
