Thank you so much for the replies. My friend gets up every morning and goes to the gym to walk the treadmill for 45 minutes.......so she is in great shape. I feel much better now about her possibly going on at least Soarin and hopefully Test Track.......We leave on Nov. 14th and I can't wait!!!!
There is no hard and fast rule as to who can go on what ride(s). Some kids love thrill rides, some kids don't. The same is true for adults and senior citizens. Each person is different and should go on those rides that he/she wants to go on. If your friend is adventurous and wants to try some of the more active rides then that's great. If not, then that's great too.
My mom is 75 and rides Expedition Everest, Rockin' Roller Coaster, the Tower of Terror and lots more. As someone else said, you're only as young as you feel!
