The wax museum at the venetian is a blast, and so is the star trek thing at the hilton(and I don't even know anything about star trek..just went for hubby's sake..lol).
We got our tickets for both for 1/2 price, about 1/2 way down the strip, opposite side of the street as caesars palace. There is like a courtyard of booths/carts with mdse for sale. You will find the 1/2 price ticket place there..they had some great deals. Many, many shows and attractions to choose from.
We loved the venetian, but decided mandaly bay, new york new york looked great as well as the Wynn of course. Oh, and the buffet at the Wynn(we went for breakfast), omg...you have to go. Totally delicious.
Get on the internet and sign up for some of the websites email specials for the resorts you are interested in. We got a great deal on the venetian. Cabs are farely cheap if you don't have a car.
