I have just found out that I am going to have a pretty heavy duty shoulder op 5 months prior to my trip to Orlando. I will still have to be careful with it and will have limited movement. I won't be in a sling or plaster though. The one thing I have to avoid at all cost is moving my arm out sideways from the body. I am hoping to still do the coasters because I will be able to hold on to the shoulder restraints ok, but I can't remember how knocked about you get? I would love to do the rides at I.O.A. including the HP ones and Manta at Seaworld. What do you think? I am a little worried about the water rides at the waterparks too. I can't remember how thrown about you are on landing in the water from the slides .I MUST keep that elbow into the body to protect the shoulder. A couple of the smaller rides sort of concern me like the drop at Splash Mountain and Jurassic Park . I will only be able to hold myself steady with one arm and what about Expedition Everest? Can any one advise please?
