All I can tell you is that they were still doing the Make Your Own Mickey Ears (we got kits to go, though) and that they were doing an egg hunt of sorts for Easter (had to find the decorated eggs and take photos to earn a prize). I didn't look into any other activities at the resort as they have never had activities that have appealed to me.
I don't know if they ran out of Mickey Bars. Again, I didn't look (not one of my favs like Dole Whip is!). However, they were low on their other Mickey snacks (brownies, cookies, etc.) one day at Ulu, so maybe? They were replenished the next day though.
