I feel sorry for those that planned so far ahead, saved their money in times when money can be difficult to earn, and then having to go through intense security screenings and a somewhat more dangerously time to travel as recent event unfold.
And then after leaving your Underarmor HeatGear home, the wool socks and scarves you get snow, a rental car with greased tires, drivers that have this absolute total ignorance of driving on icy roads and even your lodging seems to lack in the heating, I really feel sorry for you.
Last time I left my home in Alaska to visit the parks it was january 2004, the water parks were nearly deserted but my family had a blast! The lines were less, the temps were in the mid 50's to mid 60's and yet we saw tourists bundled like they were waiting for the re-start of the Iditarod (its a dog sled race here in Alaska) and yet we were in short sleeve shirts, no jackets, no gloves.
But everytime I do leave Alaska I always carry a little bit of moderate winter clothing, at the least a wool shirt. people have fun in the snow, I would expect Disney to make the most of it, who knows this could become a regular seasonal event, snow in Orlando!:xmas:
