I know that Epcot closes at 3 pm on the 5th for the "Happiest Celebration on Earth/Soarin'" press event that is closed to the general public. I don't think there is any closed press event at MK that day - just the "official" opening of Cinderellabration at the castle. MK is supposed to be open to the public from 9 am to 10 pm that day, correct?
