Okay, I'm headed on vacation to SD in July. I need to know if anyone has a hook up with rental cars in the area. I need a full size van or something that will comfortably seat 6 people. I'll need it for a little less than a week. Anyone know the cheapest way of doing this? I got a flight and hotel lined up, but am lacking on the vehicle situation. HELP PLEASE!!

Or, can I borrow any of YOUR cars? I'll bring it back with a full tank!
