I'm looking the park hours for march 31 (sunday) and the Magic Kingdom Hours indicate just an " - ". I think it's a mistake (the EMH indicates twice 1am -3am), but just in case I'm asking if there's an special event that it's affecting the park? I can't believe it will be closed for regular visitors.

The other parks show their regular hours fine.
