"Non-Busing Locations -
Your car will be right outside the Avis facility. Just stop at the Preferred Counter and show us your driver's license. An Avis Representative will hand you your keys and direct you to your car"
I have never had this happen. Basically, I get an upgrade (although I sometimes have to remind them)and that's the only difference with Preferred. The only reason I don't switch to others is the famous "D002..." AWD rate. It generally is so much cheaper than the others,I just stay with Avis.
Overall,Select is "no big deal".
