With a rental, can I use Disney's Magical Express service to get to and from the airport?

Unfortunately not, as Disney has discontinued Magical Express services. However, you can book the same service from Mears or Sunshine Flyer for $16 each way per person. Ubers typically run $45-60 each way. You may also want to look into the very competitive car rental market at MCO. When staying on Disney Vacation Club points, you do not pay for parking at the Disney resort or the theme parks. (The parking lots were sold to DVC members in the timeshare deed. The DVC member dues pay to maintain parking lots. Free parking is extended to people renting a member's points).
