They do if they are outside, yeah. Part of the reason our first AK day was so terrible was because there was a Thunderstorm and they closed everything outside, which in AK is almost everything. We were next in line to meet Pocohantas when they closed it down. The CM was great and took the kids' books to get them signed and brought them back to us. No pictures with her, but they got the signature. But they closed all outdoor stuff. Meet and greets, coasters, walks, safari, everything except the indoor shows and the restaurants. Which also meant all that stuff was PACKED. Not a good experience. And we were soaking wet and cold and the food at Tuskerhouse was bad, the hot chocolate was more like dirty warm water....we called it and left early....handed back our dining package tickets for The Jungle Book so some other family could enjoy it, and went to bed as soon as we got back to our resort. I don't think it's as bad in the other parks because there's more indoor stuff everywhere else, but AK is definitely not the place to be in bad weather.
