Disney novice here - we are staying at AKL. I have a listing of the parks' extra magic hours. What exactly does it mean? I'm assuming if the hours listed on the Disney website say 9-9 and EMH are in the morning, the park will open at 8am for us. But....the website says up to 3 hours late for pm hours. Can someone tell me how late each park will actually be open? And....the hours listed on the site for the day don't include the extra time, right?

Thanks!
