I fly in here at the crack of ridiculous every Monday morning and am in NO MOOD. So this is just the place for me, as they spare themselves the joy of having to talk to me by letting me belong to the emerald club and pick out my own car. I used to use Enterprise but it was just extra time spent waiting in a line every week to pay and be walked to a car. I don't need to be walked to my car. I'm good, thanks. Unless you have coffee in your hand I don't want to talk to you at 7 a.m.
The setup at National is more efficient and less touchy-feely than those others, which spares ME from having to be civil to more innocent bystanders at that time of the morning. The price is at least comparable to and often costs less than other rental companies. The cars are always clean and in good condition and they have a nice selection. This week I even got a fancy new convertible mustang. Too bad it's so freaking hot I would burst into flames if I dropped the top, but still. Nice car. :-)
