The 2 stars instead of one is for the view....now the rest:
INSANELY EXPENSIVE TOURIST TRAP, don't be a sucker!
Sky Jump - extremely over-priced 100 ft fall, then you get jerked hard by your harness and fall the rest of the way just kind of waiting for it to be over and feeling sick... about how much money you've just spent on this crap.
Insanity - Kind of fun, but lasted literally 20 seconds. Most of the time you're looking at the stratosphere also, not Vegas.
X-Scream - over in 5 seconds and doesn't go over the edge unless you unbuckle your seatbelt and jump... which I don't recommend.
Big Shot - the only remotely cool ride, it gives you some serious G's on the way up! Then you come down. Big Shot is only ONE shot, keep that in mind.
If you like thrill rides, these are not thrill rides. These are tourist traps to take your money and leave you feeling robbed. New York New York has an ok roller coaster, and the NASCAR cafe's is pretty long. If you want the only ride worth your money though head way south of Vegas to Buffalo Bill's Casino and ride the Desperado all day with no line for like $20, or once for $8.
