We where at DW Easter Sunday in 2005. The rule then was if you are staying at a resort that had a egg hunt you could join in, otherwise, no.
They did have plenty of nice breakfasts though that you could make an ADR for. We went to Chef Mickeys. Let me warn you though it was just like any other day. That was the only Easter in my entire life when it didn't "feel like" Easter at all.
Don't get me wrong we still had a great time though. Have a blast!!
