I also did not remember it being very bumpy. But we were just there last Monday and took my Mom who has a bad back and we had an expecially bumpy ride. Fortunately, her back was ok, but I guess I just noticed more how bumpy it actually was. It's your choice, of course, but since you asked for opinions, if I were 6 months pregnant (again - have 4!), I probably would not go on this ride. Good luck!
