My flight landed in the morning and as soon as I walked out of the terminal I could see the shuttle pickup point (NH Hotel). At that time there seemed to be no other customers, the driver was already waiting so I didn’t even need to call. The rental office is about a 10-minute drive from the airport and the whole pickup process was pretty quick. Just make sure you bring all your travel companions with you when you go to pick up the car, because the parking lot you see right outside the terminal doesn’t offer any short-term free parking for drop-off; the minimum charge is 6€ even if you’re only there for 3 minutes.
