We accidentally ended up at WDW during polar vortex, when we were huddled up in our winter coats (from Maryland) and people were freezing and the local weather people were having to explain frost warnings and windchill readings...and it ended up being an awesome trip in part because so few people were there! Yes, waiting for Fantasmic was brutal on those concrete benches, but we're ride people and had a blast. We're leaving this weekend and noticed the sudden temperature drop with eager anticipation because it makes the parks SO much more pleasant.
