I'm trying to get pricing on the Alamo web site. I want to pick up at MCO and drop off at the Dolphin (ORLR13). When I try to select the Dolphin as the drop off location, the site says "Alamo does not have a rental facility at the location you requested" and refers me to the National site. I've read that people have returned their Alamo rental at the Dolphin. Why won't the Alamo Web site allow me to select the Dolphin as the drop off location?
