It's been awhile since we've taken advantage of the EE days at the parks. I've read that means they open 1.5 hours before the usual opening time. Say if a park opens at 9am, then it would open at 7:30am on an EE day, correct? How early do the Disney buses start running then? Could we expect to catch a bus at 6:30 or 7:00 am? Thanks!
