We plan to get our rental car at the airport and am considering Avis. I went online and saw that Avis, Budget, Dollar and National all show to have counters on premise in the airport. I have a dumb question as we don't usually do car rental from a larger airport. I assume the counter is inside, but the lot where the cars are located may be a good way off premise and you possibly take a shuttle or such to pick up your car. My question is when we return to the airport to depart back home, do we just go turn the car in at the lot and load all our luggage on a shuttle and then go to baggage checkin? Do we have to go back by the desk to turn in the keys or just how does it all work? I know you must be thinking I must be mighty sheltered, but we usually take 2 vacations per year, 1 to Disney and 1 to Key West. We normally fly into Key West so it is not an issue as we just drop the car off at the door and away we go. (If you've ever seen the Key West airport, you know what I mean) At Disney, we always stay at a resort on prem so we just take a limo from the airport to our room and use cabs the rest of the time. Any info is appreciated. Thanks!
