Also be aware that Fox is not at the main rent-a-car place but you do need to take the airport shuttle to there as your first leg. Then you need to get on the Fox shuttle or wait for it to take you to the Fox place. Then you need to wait in line, my friend in his last trip a couple weeks ago said he waited 45 minutes in line alone and will never do that again. Fox does not pick you up at the airport as no rent-a-car shuttles are allowed on site anymore. Not knocking them but I was always able to get close to their rate by booking with Alamo or Dollar.
