but on the 3rd day at Magic Kingdom my right-knee buckled and I couldn't walk at all. I ended up getting a scooter and a disability pass and crutches. I couldn't put any weight at all on my right knee. Luckily on the 4th day I was able to walk again, albeit with some pain.

I did 10-days in Orlando in October including 7 at Disney, 2 an Universal and 1 at Sea World. This last trip was the end of January. This last trip I had a park hopper and after the 2nd day couldn't use it.
