Next trip we need to rent a car for at least a few days to pick up friends who are staying with relatives. I figure the cost for a couple days will be close to what we would spend for a day trip anyway. If we rent a car for the week at the airport, how much time should I allow to turn in the car and get to the terminal in addition to the 2 hour advance arrival requirement? We depart at 6am. Last trip we took a 7am flight and the taxi drive took <15 minutes from south strip.
