I live in central California and was thinking of using LAS as my primary airport for my flight travels instead of SFO or LAX. Flying out of LAS is way cheaper whenever I have to fly cross country. I figured that I could drive to Vegas the night before my flight, stay in a comped CET property, then take off. When I return several days later, stay again in a comped CET property a day or so before driving home. My question is, does anyone else do this and just leave their vehicle in the casino parking garage while they're gone? Or maybe valet? If you make arrangements with the casino first, do they even mind you leaving your car there while your'e away?
