Day 3, #3
There's a good shot of the Stratosphere. Yes, the hotel and casino are at the base. You can take the elevator up to the top where there are arcades and stores and all kinds of stuff on the way up to the viewing deck, lounge and RIDES. The roller coaster (not kidding) is seen as the red metallic track running around the upper part. The thing metal spike on top holds a platform that shoots you up to the top and then bounces you up and down nearly the length several times. More on that later though. :)
