Has anyone expirienced this? I was at MGM and wanted to take the Disney Transportation to DTD, the sign showed service after 3:00 pm only, and no return service to MGM. We were under the impression that we could catch a bus back to at least one of the parks. No such luck, there are only buses to resorts available, for resort guests only. We managed to get by on a technicality, they forgot to change the sign on one of the bus stops at the marketplace showing a bus to the Transportation Station so the driver let us get on. Long story short, apparently there is no way to get back from DTD for non-resort guests except for paying for a cab.
