Is the car rentals at the airport? Or do I have to a ride to the car rental

Depending on which car rental agency you use there's a shuttle that will take you there

It is all shy but there is a shuttle to get there

It's off the airport. You will have to take a shuttle. The shuttle will take you to area with car rental services..

Beyond luggage pick-up/drop off area, there is a shuttle bay to take you to an off-site location where each rental place is on a strip. Not close enough to walk between though, so be sure to take the correct bus

It’s off airport, you need to catch a shuttle bus.
