We just got back from the Easter cruise on the Wonder. When we boarded, all of the Cast Members were wearing bunny ears and they gave my DD a coupon to redeem for a bag of goodies including a small bear or a big plastic jelly bean, and a few candy bars.
We brought the Easter Bunny with us and had a small egg hunt in our hotel room before we went down for breakfast. I packed DD's Easter basket in a cute beach bag with stuff that she could use during the cruise.
Some people ordered baskets from The Perfect Gift or through DCL.
