We are scheduled to arrive in Orlando at 4:20 and have reservations at Restaurant Marrakesh (Morrocco) at 7:30 (it was 7:00 but that made me nervous!). We are taking DME to POP. As I understand it, my primary mode of transportation to Epcot would be a bus to the front gate followed by a long walk back to Morrocco. Is it possible to just get a cab from POP to the International Gateway? I don't want to have to rush and while I am sure a nice, leisurely walk would be welcome after sitting on plane I am sure I will get enough walking in at the airport, etc.
