Though it's beyond gimmicky (who was the big brain behind this name?), THEhotel is anything but corny. In 43 stories rising above the Strip, it's got the largest standard rooms in Vegas (a measly 750 square feet). The place is a playground packed with cosmopolitan fun: the 1,117 one-bedroom suites with wet bar, marble bathroom, plasma TV; the Bathhouse Spa with its pools of different temperatures, baths and flowing waterfall; and the swank Lounge (with delish cocktail concoctions) on the very top floor. Don't be fooled by December's ridiculously low rates; THEhotel is a sizzling Vegas destination.
