Hi, all! DH, DS3, and I are going on our first WDW trip in October, staying at GF. I wasn't planning to rent a car for the trip, especially with the new *free* Disney transport to the hotel and back, and expecting to use all Disney transportation while we're there. BUT, my grandparents live in Largo, FL (outside of St. Pete), and I wanted to take a trip down to see them one day during our trip. I asked the concierge about car rental companies that are convenient to WDW (I have a friend who lives down there and works at GF and would probably drop us off and pick us up). The concierge mentioned that Alamo and National are the "official" rental car companies of WDW and would pick us up/drop us off. That's very nice, BUT, my American Express rewards program only offers certificates for Avis or Hertz. I'm quite sure I will be able to pay for or almost pay for a one-day rental (probably a nice one, too!) with my certificate, so I'd really like to use them instead. Anyone have any experience using Avis or Hertz to rent a car at DisneyWorld but NOT renting through the airport locations? Suggestions, experiences, etc. are greatly appreciated. Thank you!
