We survived! Almost twelve hours at the Magic Kingdom and my knees and feet held up wonderfully! I had no pain all day, walked the whole park, seemingly in circles. Last year I would not have made it from the handicap parking to the gate. The kids did wonderfully, the only meltdown was done and over with the first five minutes we were there (the three year old thought he should have cotton candy at 10 am). Perfect weather.
Sherry, I do still feel tightness and swelling, mostly in the right knee. Probably more tonight after a day at Disney. I could use some ice, but I can't seem to find a bag that doesn't leak. And as noted a couple posts ago, I had a really painful 24 hours a couple days ago when a low pressure system went through. I know there are still many months of that to go, but it really was a magical day at the Magic Kingdom that I was able to walk as well as the rest of the family!
