The problem is that the DHS bus to the EPCOT finish line also says it doesn’t start running until 7:30am as well. From the guide, there seems to be a transportation dead zone from 4:30-7:30am. Someone correct me if I’m wrong, but the only transportation option to the finish line between 4:30 and 7:30 is the monorail. And I’m not seeing a great option to get to TTC. This may be a convo with someone at guest relations at the expo, but their best option may be to get to DHS before 4:00am. But this is a new situation so I can’t be positive here.
