I have been waiting for B&YC Easter activites to be posted somewhere - I've found every other resort except that one! I'm hoping the info will be out tomorrow but if it is as it's been in the past, there will probably be a candy scramble around 9 am, maybe w/characters, and then some fun pool games/activities in the afternoon. Probably something on Sat also.
Only thing I've seen at MK for Easter is Mr&Mrs Easter Bunny - last year we saw them in the small garden at the start of Main Street to the left (near the firehouse).
