Here are a couple of sites for you to check out for Las Vegas. This one http://www.a2zlasvegas.com/ has everything you ever wanted to know. Pretty good reviews for shows, restaurants, hotels. Or you can check out the Sunday LA Times travel section which always lists special prices in Vegas.

We've stayed at Ballys which is located right in the middle of the strip. You can check out their site where they special prices available. We're going next week for a couple of nights for $49. http://www.ballyslv.com

Hope this helps. Eileen
