We're taking out first family trip to WDW this October, myself, DH, DS4 and my mom "Grammy". Our planning so far has been all about DS4, who'll celebrate his birthday on the DIS cruise after our 3 days at WDW. But I want to make sure Grammy has a good time too, and that the 3 days at WDW don't take too much out of her. She's moderately active, but has the usual aches and pains; occasional trouble with her knees. She won't want to be in a wheelchair or anything like that. I've thought of taking the little outdoor stool (tripod shaped that folds up with a strap to throw it over your arm) so she can rest while we're in line. Also thinking of timing in some rides on the trains, etc. to pace ourselves (DS4's into trains so he won't complain). Any ideas?
