Crowds during Star Wars marathon weekend

I have an ADR for 8am at Akershus on Sunday April 7th which is the day of the Star Wars half marathon. I also see that the marathon ends at Epcot. Am I going to have a hard time getting from POP to Epcot that morning? I plan on taking the bus but am wondering if Minnie van would be a better option. If anyone has any experience with this let me know! Thanks
