$14 per person isn't great. We waited in line for the first car, didn't wait very long at all. They have lockers for $.50 that you can put purses/jackets/phones into. It does go upside down, so it may be worth just locking away some of the personals and not worrying about it.
The rollercoaster itself was great. Two nice, big drops to start, some upside down loops and corkscrews... what more can you ask for from a coaster?
If you're a nutjob, you can get an all-day pass for $25. It would pay for itself pretty quickly. It's definitely worth considering.
Fun change of pace. Consider it an alternative to a couple minimum bets on a roulette table.
