Getting from GF to AK on Marathon morning

[Deb & Bill]

I want to get to the AK to see my husband run through the park. I hope to catch him run by the GF after he leaves the MK. Do the buses run from GF to AK around 7:30 to 8AM in the morning on Marathon Sunday AM? I'll need to get back to Epcot and hope I'll get a bus there, too. I know I can take a bus to Epcot from OKW, then the monorail to MK. It's just afterwards that I want to make sure I can get there. Roads closed between AK and GF?
