It has been 13 years since I've been to Disney World and I've never stayed on Disney property in Florida. By the "pretty" illustrated maps, Port Orleans Riverside looks closer to Epcot than the Swan or Dolphin hotel, which I know are walkable to Epcot. So is it possible (and would it be easier) to just walk to Epcot from Port Orleans Riverside?
Side question: I have a reservation for the California Grill for dinner at 9:20pm. Can I arrive early to watch the fireworks from up there?
