Nowadays, airports rarely have on-site rental agency. So airports have developed an off-site rental car center where most companies can conduct business. This makes sense. Yes, as a consumer it adds additional time to get and return your car, so you should adjust your time accordingly. This center is not near the airport, but the shuttle gets there rather fast. My only issue is that wait for an entire shuttle to fill up before leaving. If you are one of first to get on, you will notice that the last 10% of the folks coming in are 20 minutes behind you. They have enough shuttles to take 80% capacity and more more frequently. Meanwhile the actually center is large, has a big seating area in case you have to wait for others and is nicely arranged. It's one of the better ones.
