I push my Mom in a wheelchair at
Disneyland regularly for 1-3 day visits. But WDW, she rents a
scooter as I cannot push her for 10-12 straight days. She is not super heavy, but one quickly learns how many hills/inclines really are in the parks. I never realized until I started pushing a wheelchair. And there are a few that I just make her walk for a few minutes because they are just too much (I am looking at you bridge the Paradise Pier at DCA or bridge into Critter Country at Disneyland) or take a longer, flatter way around.
