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 for a much lower price.
A Dinner and Show combo is a great value and saves time to do other things that day.
