If you choose to do this, definitely look for the 2 for 1 coupon that they have circulating in a Vegas coupon book. A really nice woman behind us gave us one and we didn't even know about it, but it'll save you $10, so definitely find one!  It's a good experience to be able to get up that high, but there's only so much time you can spend looking down on Vegas and for about 10 minutes, it's not worth more than $10.  Also, if you're afraid of heights, don't spend your money on this! You're safe up there, but still, I felt very woozy!
