My mom decided 2 weeks before our trip that she was going to get a partial knee replacement. Her Dr suggested it a long time before our trip and she talked to him 2 weeks before and he said "hey I have an opening tomorrow" she of course said ok - she reassured me that he told her " you'll be out doing gardening in a couple day" I told her that is a little different then 8 days at DW but this was her first full stay there usually she has only gone 1 or 2 days. Anyway I called and had a scooter for her because I priced them and it was cheaper getting it off site then at the parks. She had a great time she was able to walk and stuff when she wanted but if she got sore or tired she had the scooter. Now her driving skills another story she went to get off of it at the Grand Floridian and thought she had it off but instead had the throttle all the way up and she hit the throttle and almost ran over DH getting DD out of the stroller and ran into a picket fence and almost knocked it over.
Man good times we still pick on her about that!!!! I have to tell you the funniest was at the CR in the main elevators we were going to the lobby and she had to reverse out and there was a huge crowd trying to get on our DS8 was behind her by the door when it opened he yelled "Go Mama" as soon as she went to reverse out he jumped behind her to get out of the door first and she hit him she was not happy and DS was lodged up between the door and her scooter and she said "get out of my way" and DS yelled "I can't mama your on my foot!"
We will never let her forget that one. Have a great trip I am sure she will be fine but I suggest a scooter
