Cheap stuff that is fun? Walk the strip! Check out all the themes of the casinos. Best part is walking around with an open container. Then stop off for the free volcano show at The Mirage, pirate show at Treasure Island, The big ass wheel, water show at Bellagio, go to the top of the Eiffel Tower at The Paris, go on the roller coaster at NYNY. Lots of fun stuff that doesn't revolve around gambling and grinding at clubs.
