My daughter has been completely non-weight bearing for the last 3 trips (she shattered her left leg.). This will be her first trip since the accident where she will be able to ride rides. Pirates will be very difficult for you. One foot or the other will need to be weight bearing to push out or pull you up out of the boat. Also, should the ride break down, the walk out isn't easy. Similar for Splash. Remember, if you step down into a ride, you will need to step up out of it. We did 3 trips, and learned just how much she couldn't do. But to be honest, I preferred she skip rides, than injure herself trying to ride. Remember, if you get walked off BTMRR, you will need to get yourself out of the car, over a ledge onto a set of rock stairs that you may have to go up or down depending on where.
A year ago I got walked off Casey Jr. There is NO WAY my daughter could have done that one on her leg. You would never think it would be a rough exit.
And to clarify, Cast Members are not allowed to assist you. They will be allowed to hold your crutches and place them in the wheelchair area while you ride. But you must be able to et into the ride vehicle and out of it quickly on your own. I say quickly because rides like Matterhorn, Big Thunder, Splash can back up and estop if you are unable to load or unload is a very short time.
