Avoiding long car rental queues at Orlando

[cashmax]

Flying to Orlando on 24th May, so about 3 weeks. Desperately want to avoid queuing for hours for a rental car. Any advice that might speed this process up. Not a member of any loyalty programmes, so not sure if it's too late to join? I do have a Sixt express card, but its not clear if this will be of use at MCO??

Just to close this off, the flight was 15 minutes early, we walked into an empty immigration hall (literally, there was no one else there at all), bags were ready. The Alamo fast track worked perfectly. As a result, from walking off the plane to sitting at the exit of the airport in the rental car was - 36 minutes. The quickest ever long haul experience I have had, by a LONG way.
