I was all set to try Tower of Terror on my last trip when my husband said maybe I shouldn't go on it - so I didn't. We're planning another trip in April, and I'd like to hear from others with back and neck problems who have gone on it. Do you feel it can be hard on the back and neck or is it pretty gentle? I used to love free-fall rides when I was young and would love to try this if it won't bother me.
