Poolside cabanas are the new nightclubs. Here, four of the coolest.

Most Opulent The cabanas surrounding Wynn Las Vegas’s "European" pool (read: tops are optional) are not so much tents as airy studio apartments, outfitted with plasma TV’s and marble-topped bars.

Best by Night The Venetian’s Tao nightclub added its own beach club earlier this year. By day, you can retreat to your cabana and play Xbox, indulge in a massage, or surf the Web; after dark, hit Tao Beach’s floating dance floor, ringed by 14-foot-tall columns of fire.

The Classic Hard Rock Hotel’s thatched-roof huts not only give you wraparound couches, personal misting systems, and LCD TV’s but they also grant you access to Rehab, Vegas’s hottest pool party (all day on Sundays). The downside: cabanas are booked months in advance.

Best Deal The Flamingo’s GO Pool cabanas give you a plasma TV, bottle service, and a fruit platter that could feed 40—all from $250 a day.
