The Stratosphere might be downscale compared with other Vegas hotels, but there ain't nothing "down" about the high-in-the-sky experience to be had here. From this sleek, attractive room, the view of Sin City is truly amazing (if slightly remote). For an even bigger thrill, head upstairs and outside (to level 108, of course) to AirBar. The signature drink: something called Jet Fuel served in a souvenir cup. Consider yourself warned.
