The zealous American grandparents have v. kindly invited us to Disney World. Unfortunately, my dad, who just had a hip replacement last year, now needs a knee replacement and finds walking v. difficult. I wonder if any of you Disney World veterans have noticed if they hire out electric wheelchair thingies (my mother describes them as sort of motorized carts) which are evidently quite popular in America. I've not been able to get that info from the website. My dad is NOT the sort of person who will agree to being pushed in a wheelchair, so it'd have to be something motorized or electric, or nothing at all. TIA
