Sort of right when I figured actually, based on Summer 2018 on the website for the past few weeks.
Memorial Day is not summer, June 30th is, by about a week. So right on time, based on that.
I know, I know, Memorial Day is the unofficial start of Summer is most everyone's mind but it is still not Summer. But June 30th is.
Bummer for our end of school year trip though. Now we can only hope that it lines up with any potential passholder previews
