TripAdvisor.com has officially chosen The Signature at MGM Grand in Las Vegas as the No. 1 "Best Luxury Hotel in the U.S." The TripAdvisor's 2008 Travelers' Choice Awards also recognized The Signature among the "Top 100 Best Luxury Hotels in the World" and the "Best Hotels in the World's 25 Most Popular Destinations." What makes the win so interesting is that the Signature does not offer a casino, is non-smoking only, and all-suites - no standard rooms here. While it is true guests can still use the MGM Grand for gambling and smoking, by booking the Signature, they get to enjoy a gated entrance and suites with balconies.

Note Bene: At 550 square feet, the MGM Signature Junior Suites are big on style and are the most basic, standard room category.
