Hannah, you're gonna love everything about your time spent there, and I have a bit more to add to what's already been said:
When going to Las Vegas, you must visit the Forum Shops at Caesar's Palace. The Forum, a huge, covered fresco-style mall, is designed in a manner similar to the streets of Rome in days of old. You will find larger-than-life statues of various gods and goddesses. Adding to the open air atmosphere, brilliant skies and clouds overhead amazingly change in color to reflect daytime and evening. If you've ever yearned to go to Rome but have not yet made it, you can trick your mind into believing that you're actually strolling the streets there. It is soooooo breathtaking -- be sure not to miss the Trevi Fountain replica. Spiral escalators are spectacular -- they even had a fashion show beneath them.
The Forum shops are high-end and pricey but window shopping is free. There is more than haute coutoure fashion, like glassware, china, jewelry, and some fantastic art galleries! Walk among the 'real' money shoppers and enjoy yourself, whatever your tastes dictate.
As far as restaurants go, we ate most meals in some really nice hotel buffets...low cost and great variety, especially dinners at Sahara. But our driver tipped us off to the wonders of breakfast buffet at Circus, Circus. They must have 1,000 items there from which to choose.
A word of caution -- if you are approached by anyone offering free dinners and show tickets in exchange for attending a brief off-site program, run like hell. We fell for one of those schemes that turned out to be a hard-sell tour of time-share condos somewhere far from our hotel. Of course, they expect your signature on the proverbial dotted line, saying you'll buy into the program. It would have been much easier if we had been in a position to join up, but they made us say 'no' to at least 3 different managers before we got the shuttle back to the the hotel.
Yes, we got the dinner and tickets to a show, but it wasn't really free at all. It was like being held ransom for nearly 4 hours! Other than that unfortunate run-in, we loved Vegas...it's a wonderful town Everybody should go there at least once!
