I picked up a car today. I had reserved a full-size sedan.
No pre-arrival confirmation of your car. Instead, you get an email saying pick whatever you want from the President's Circle section, which is one long row of cars on each side. It's about a 15-minute walking from the gates, not including any time at baggage claim. The walk is partially outdoors.
Today the President's Circle rows had just about everything. A couple of Dodge trucks, a GMC Acadia, a half-dozen 2019 Chrysler 300 S sedans, a couple of Chevrolet Malibus, some vans and the like. I even spotted two Chevrolet Tahoes, one of which I was tempted to get. There were three Infiniti sedans in the premium, upgrade section.
In the end, I went with a black 300 S with seemingly all the options except a sunroof and navigation. Only 2,300 miles on it.
No water given at the exit gate.
