We have rented numerous times with Judy of Croix. They meet you at the airport and take you offsite to complete the paperwork. When leaving, you leave the car in the lot with no need to check out. They usually are cheaper than the on airport national brands, although cars may not be as new. The only other agency we have used is Budget. There is always a line to pick up your car and their customer service is not good. I have read good reports for Centerline also but don't have any experience with them.
