One thing we normally do is just go to the hotels. They're pretty impressive. The Bellagio, Paris, Mandalay Bay, the Venetian are all fun to see. Parking is free at all the hotels, even valet parking (but, of course, they expect a tip).

I always find Hoover Dam interesting. If you're with your significant other, chances are she'll like the Forum Shops (between Caesars Palace and The Mirage). I really liked the aquarium at Mandalay Bay, although it's expensive for what it is.
