I went there for a few days last summer (2 nights...which was not long enough!). Anyways, depending on where you are staying and if you plan to go to all of the casino's prepare yourself to walk, walk, walk, and walk some more! I stayed @ Circus Circus (the 5th largest hotel in the world that was packed and had thousands and thousands of people in it which drove me up a wall!) which is on one complete end of the strip, so we had to walk very very far to get to some of the casino's. If you don't plan on gambling, just be careful when you are walking around the different hotels and casinos, because they are REALLY big and you can easily spend hours in just one of them and still not see half of it. Caesar's Palace has a HUGE mall called the Forum shops. This place was sooooooooooooooo big, I know that we stayed in it for at least 2 hours and did not see the entire thing. Each hotel is themed extremely well and they try their best to keep you in. Funny as it may seem, though..my favorite place that we went to was M&M World! It was a four story store with all the m&m products you could ever imagine! Another one of my favorite things that we did was the Freemont Street Experience...it was sooo awesome! Freemont street is the old strip that they closed down the road and covered the street with a canopy that has thousands of lights. They put on a light show every 20 minutes or so. This is also the place with the neon Cowboy that is seen in Honey I Blew Up the Kid (or whatever the name is).:sohappy:
Sorry this was so long, but if I think of anything else, I'll let you know!
