we did lentgh of stay stroller rental(double stroller) for our ds3 and ds8 for 7 days it was a life saver...we new our ds3 would not make it walking that much we decided on the double in case our ds8 could not take all that walking and I am more than glad we did...the strollers were good size and easy to use...we did park hopper and it was nice to go from park to park and show our reciept and pick up our stroller without waiting for the most part...make sure you tie something to your stroller to make it easier to pick out of a crowd ..they give you a name tag but when they are lined up you cant tell sometimes...the only down side was at the end of the day ds3 had to be carried to the buses and to the room because he was just too tired..would be nice if you could get stroller to use to the bus and when you get off the bus at the resorts..but overall it was the best tip we took advantage of...we are going back in Nov and plan to do it again...by the way ds3 is the size of a 5 yearold and my ds8 is normal size and together they had room except at AK those strollers are a little more cramped but still worth every penny we paid...have fun!!!
