As a President's Club member, they've almost always been automatic. As SFO777 said, if we don't like the car that's in our space, we will go back to the kiosk and ask if anything else is available, and have almost never been denied a choice between a couple of other options.

Also, President's Club is supposed to get a two-category upgrade if available. We usually reserve a mid-size / intermediate, and have often been upgraded automatically to a premium which is a triple-category upgrade.
