Take a helicopter tour over the Grand Canyon. We did one and it was so much fun. They fly you over into AZ and there is a working ranch at the bottom of the canyon that you stay in (included in the price). They serve dinner and then you stay the night in a little shack on the property and then you have breakfast (all food included) then you fly out. It was pretty cool.

The casinos are the only other things to visit out there. It's a pretty poor place other than the strip from my experience. New York New york has a roller coaster that is really fun. It's big and it overlooks the strip. cirque de soleil is a must see show.

Have fun.
