I have never gone more than two days without riding the Monorail but many People have come to Vegas a 100 times and never once ridden it. The best reason to ride it is to get to and from the Flamingo/Quad/Harrah's part of the south end at MGM. all the other stops are not as popular but that route is because You can really save some walking and time.
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.
