This 3,933-room Italian "villa" is the embodiment of Vegas luxury. The elaborate Italian-themed courtyard is one of many highlights, with five swimming pools, elaborate sculptures, and fountains. Rooms are sophisticated and contemporary, and all have marble bathrooms with separate glass showers and soaking tubs. Guests (mostly couples, and a healthy dose of families and business travelers) will find formal room service, a superb fitness center and spa, and the best buffet on the Strip; attractions such as the indoor botanical gardens and the dancing fountains are world-famous. Cirque du Soleil performs here, and the massive gaming floor is one of the best in Vegas. The Bellagio has prices to match its five-pearl service; in terms of competition, only the Encore and the Cosmopolitan can compare.
