Topic I am interested in myself. If staying at an EPCOT resort can you walk through for the start? Or do you need to take a bus to the entrance?
If you do an epcot resort you can walk from the finish line area back through Epcot to your hotel and not have to deal with the bus transportation, which can be spotty. We've done that the past 3 years. If not those resorts, then I'd def say BLT!
