Rod,
The wife & I go twice a year and have seen most of it. I would say go to the Stratophere and eat in their restaurant. but go at sunset because it rotates while you eat and if you time it right you'll see it all & when the lights come on at night, there is no better place to get a view. also, if you have the guts and like extreme rides, thier are a couple up there that are a blast.
