The activities and extras that came with Howl-O-Ween aren't anywhere near as extensive as say going to Mickey's Not So Scary Halloween party at Disney World. You get a few pieces of candy, some fun Halloween pictures, and get to do some low key Halloween activities. That being said, I think Great Wolf in general is worth the cost if you can get a decent deal on a room, so the extra perks from Howl-o-ween are just bonuses to me!
