I have done the Flying Dutchman. It is a fun experience. I am also above the age range that you mention.
I would recommend the flying Dutchman. Anybody on the ride should have mobility,. You sit in a chair and you are harnessed in quite well. The stop at the bottom has a slight jolt. Nothing to extreme.
There is a bar at the top of the ride and some people take a shot prior to taking the ride.
