Things like expedia vacations are good, but not as good as some of the airline packages -- especially for 1st class air.
Why not take the Air+Hotel. Sometimes it's just as cheap, and it comes with a hotel room that you might be able to use. As I said, you might get a coupon book with real value, plus you might get on the hotel's mailing list for future discounted trips and special offers. Plus, as I said, if you are staying on the Strip but have a free downtown room you can use it for a quick rest or to have a place to go to the bathroom. If you go to the bathroom in your rental car you will end up having to pay a big fee when you return it.
