Last year I hadn't even considered a stroller for DS4 since he hadn't been in one for years.....he's just non-stop energy so it never crossed my mind to bring a stroller or prepare to rent one! We wound up renting a stroller for one evening when he really was just tuckered out.....even though he's a very active kid, Disney walking was really much more than he typically expends, energy-wise, each day and he asked for a stroller, so we got him one - next day he didn't ask, so we were stroller-free for the rest of the trip. I still wonder if it was that he really, really needed one, or just that he saw other kids in strollers and wanted one too? Who knows - all I know is I was tired by the point he asked, so I'm of the opinion he needed it - heck, I would have liked one too, but couldn't find any volunteers to push me around!! LOL
