Vegas Hotel Shuttle Buses are a free service. They are meant for anyone that is going to gamble at the destination of that bus so if you are not going where the destination is (like a neighbor casino) just be sure you act like you are going to gamble where the bus is taking you.

With more shows to choose from than any other City in the World, You might feel overwhelmed deciding on one. But if You narrow Your preference to a category, You can make Your decision much easier. If Your interest is in a Cirque du soleil show, why browse through the Comedy and Adult shows? If You want to see Britney or Mariah or JLo just browse the Concerts and headliners.
Don't like huge theaters and big crowds? Choose an afternoon Show or a half price show.
A Dinner and Show combo is a great value and saves time to do other things that day.
