Las Vegas visitors and residents have many opportunities to explore great entertainment options. Granted that tickets aren't always cheap, the shows are usually amazing and the venues exciting. There are some Strip fixtures like Celine Dion and the Cirque Du Soleil shows and then new acts that seem to rotate in and out of town.
The venues, including Bellagio, MGM Grand, and Caesar's Palace, offer up great rooms and hospitality. They also provide easy access to many other forms of entertainment.
