Height definitely helps when it comes to enjoying rides. I'm 6'1" and greatly enjoyed Vortex last year when I had visited! I also enjoy Vortex, Dragon Fire, and The Bat at my home park, Canada's Wonderland. I also enjoyed my ride on The Bat (AKA Top Gun/Flight Deck at Kings Island as well last year. I like it how I don't bang my head against the restraint but, I sometimes knock my knees depending on where I sit on an Arrow Dynamic looping or suspended coaster/train. I prefer sitting in the front of each car when it comes to riding Arrow Dynamics' coaster but, when I rode Adventure Express last year, luckily I had no problems with it in terms of knee knocking because the cars were quite spacious!
