Forbes.com list The Mansion at the MGM Grand in Las Vegas as the most expensive hotel in the world. Prices run from around $5,000 per night for a two-bedroom villa to $15,000 per night for a 12,000-square-foot villa that could easily accommodate eight people. Meals and alcohol are charged separately. What guests are getting for their money is plenty of space--the villas range from 2,400 to 12,000 square feet--as well as original Picassos on the walls, and the prestige that comes with being able to afford a room there. Modeled after an 18th century Tuscan villa, the 290,000-square-foot structure houses 29 villas all richly appointed in a mix of casual and elegant furnishings. The traditional Tuscan styling of arches, high-vaulted ceilings and carved decorative wood doors is complemented by the Mansion's eclectic 800 piece art collection. The mix of new and old artwork, tapestries, artifacts, and photographs hail from around the globe and weave their way throughout the public and private spaces. When not relaxing in the splendor of their own room, guests are invited to take advantage of the seven major public areas located throughout the mansion. Far from the noise of the casino, guests can sit fireside (though perhaps not in the summer) in the Grand Salon, sip cognac and play a game of billiards in the Great Hall, watch their favorite DVD in the state-of-the-art Screening Room or unwind in the Spa steam room. A walk into the courtyard reveals a lush Italian-style garden and a pool with limestone fountains and tiles and antique stone urns. Guests will particularly appreciate its attention to detail: the heated tile floors in the bathrooms, the Limoges porcelain, the way the staff keeps track of which spa treatments you prefer and what kind of champagne you drink. Should you so desire, each villa comes complete with a private butler, though you'll hardly need one. In nearly every room, trilingual (English, Spanish and Chinese) touch-screen remote controls)--and subtly camouflaged by gilt picture frames--allow you to adjust the lighting, fireplace, drapes, music, etc. Two highly trained chefs, specializing in Continental and Asian cuisine, are at the disposal of The Mansion's guests.
