Renting a car in Las Vegas is super easy. The rental car companys are all at the same place, just hop on the rental car bus at the airport that takes you there in about 5 minutes. I always look for a rental car code or bid on Priceline and do pretty well. A cab from the airport to your hotel is about $15-20 each way and if you take a cab up and down the strip a few times it starts to add up. If you want to go off the strip to see anything, like Hoover Dam or to go downtown, just so much easier and cheaper to drive yourself there. We like to go to a few off-strip casinos so works out best for us and we always make a trip to a grocery store too.

As for the Luxor, they were pretty generous with the comps we got also. I do have a players card so got a nice rate to start with.
