Hi all - was dropping off my rental at PDX last night and decided to walk through the non-Exec aisles to see what was on offer. In the corner, I noticed an area with some nicer cars (a couple of Volvos, a Saab and some SUVs) under a sign that said "VIP aisle." Does anyone know what the VIP aisle is?

As an aside, how does Emerald Reserve work? Do I need to go to the counter to get the car? From the website it looks like you can go straight to an aisle to get your car. I was contemplating renting a premium car next rental, but I didn't see a "premium" aisle at PDX (or anything that looked like a premium car other than what's in the VIP aisle).

Thanks!
