i need a minivan in June and found an incredible deal at Payless, Advantage, and Sixt. I know the disadvantage of the shuttle, but it actually works for us on this trip, as we have to wait at the airport for someone and have the time to split up and get the van. Anything I see reviewing the companies is pretty old (but not good). Can anyone give me any new info? One to use? One to avoid? Payless is Avis/Budget so that seems good to have as a backup if they didn't have a van. Help?!?
