Grand Canyon. Besides making your own program for the trip, there are tons of tours being offered, which include transportation from your hotel or a specified location on the Strip. One of my favorites is the train tour with an overnight experience on the train. You'll take a bus coach from the Strip to Williams, Arizona, and from there, the train tour, with everything you need included. Other tours include plane and helicopter tours, bus tours, rafting, hiking, camping, off-road/safari tours, and other cool things, like gold mining and horseback riding. Do your research and really enjoy the whole journey!
