I dealt with the "what will people think" issue years ago when my foot bone problem got worse and made it physically impossible to tour WDW on my own steam. I used a push wc for many, many trips, but still felt funny about trying the
ECV. The great people on this board encouraged me to di it, and it's one of the best things I ever did. The fact is, you can walk however much you can walk. What people may or may not think will not change this essential fact. You need to do whatever will enable you to do everything you would like to do, without pain.
Cheshire Figment, LOVE the "would you like to trade with me sight unseen" comment! But Chi-mom, don't let that make you think that people will be flocking to make stupid comments. I've had people step in front of me or dart out more times that I can count but no one has ever come out and said anything to me about my wc/
scooter use, and I have taken at least 8 trips with mobility assistance.
Do what you need to do to have a magical trip! Please don't let your perceptions about what you think others might think prevent you from really enjoying your trip.
I also vote for off-site rental (I used Walker). The scooters are better & easier to manage and you won't have availability concerns. Go for it!!! I wish I moved to the scooter years ago, I will be renting again even if my dh is available to push.
