Thanks a lot, wayneg - that is really helpful!
Handy if you want to avoid the hard sell from the usual rental counters; I got ripped off by Alamo about 10 years ago (this was at LAX), so I try to avoid using them, and this is one of the reasons why I have used
Avis Preferred the last couple of times.
Do you know if it is just Dollar Express and Avis Preferred that have the rental kiosks in the parking garage, or are there any more?
I have read on the DIS Transportation forum that National have an "Emerald Isle" for members (free to join, as are Dollar Express and Avis Preferred) where you can choose your car. Therefore, if you've paid for a midsize, you might get a fullsize or SUV if it's in the same line, at no extra cost. I have never tried this, as it seems a bit complex, and I'm not sure if it even applies to international rentals or not!
