Has anyone booked a rental car through this company? If so did you have any problems or concerns? My husband and I are looking to book our rental car for our March trip but I don't know anything about them. I would like to use them if they are cheaper than Hertz or Avis but I am worried about being surprised with charges that don't tell me about, not being able to get in touch with someone if we have problems or the car breaks down, etc. Any info would be greatly appreciated.
