It's probably too late for this but if you haven't gone/left yet.
At night go to the stratosphere top of the world restaurant...I don't remember the name of the bar but order 1 drink at night and enjoy the view of
the Vegas lights. I like the hookah lounge's atmosphere, I've only been to the one on Maryland not Sahara, cirque's Ka is a wonderful show, blue man
group is ok, check out the art galleries in the casino's and the seasonal displays (always a nice free activity), interesting thing is to go to the
coca-cola world/factory and for $7 you get to try 16 different soda's from around the world. Off the strip there is the ethel m chocolate factory
where you can tour but it's better at the holidays when they put up lights in their garden walk area. The obvious choice of check out Fremont street
for an older feel and cheap eats and the canopy show at night. If for some reason you decide to check out a movie the Palms has a nice movie theater
unless you're staying way north then you might want to try red rock. Speaking of red rock you can go hiking or even hit up mount Charleston.
If you want to save $ and make your drinks in your hotel room, check out Lee's discount liquor on Sunset (behind the Outback Steakhouse). Cheap liquor
and mixers and a ton of choices. The have another one closer to the strip but it is smaller than the one on Sunset.
Hope you have/had fun on your trip!
