For a real thrill, try the Big Shot at least once on a trip to Vegas. Once may be enough for me! You are literally catapulted at lighting speed upward! A bit like freefall rides everywhere else, only you are already some 1000 ft. atop the Stratosphere as it is! The freefall drop back down wasn't the most hair raising part of it to me, the feeling that you are literally going to fly out of your seat on the swift ride upwards is what got my equilibrium all shook up!
And while you're up there, take a walk around the glassed-in observation deck. Only, don't make the same mistake I did of getting too close to the glass without watching your footing. There is a cement foot barrier at the base of the windows which caused me to trip and slam against the glass, looking directly down at the street below! Thank God for extremely thick glass!!! Not on the ride ticket...
