Mostly spent at the northern half of The Strip, walking around and seeing the sights.
 
  

I was only in Las Vegas for 4 nights (but this was reduced to 2 full days once the flights in and out and the Grand Canyon trip were taken into account), and I didn't get chance to see any shows, except for a few of the free ones - the circus acts at Circus Circus and an Elvis impersonator/tribute act at the MGM Grand.
I was staying at the Circus Circus - one of the older, cheaper hotels at the north end of The Strip. It was OK - the room was fine and as I was in Las Vegas to see the sights, I didn't want to pay too much for any fancy accomodation. The 'all you can eat' breakfast buffet was good - although it got poor reviews in the guide books, it was advertised as 'New and Improved' and was excellent value for $6.
 The view north, along Las Vegas Boulevard. Treasure Island is on the immediate left, and the Stratophere Tower is visible in the distance.

The Stratophere Tower - the view from the top was impressive. Even better than that was the roller coaster ride on the top - called the 'High Roller', it was a fairly gentle ride as roller coasters go, but being so high up, the view was great.
