The area we live in closes the schools for the entire week - they close for the two convention dates and they float other holidays that would have been held one at a time (like Columbus Day, Veterans Day, maybe Election Day) so they have a weeks' break. I believe this was first done as a cost-cutting measure, some nonsense about shutting down furnaces and then starting them up again cost more than just shutting them down for a week. We have travelled to WDW during this week, both with or without kids and have had a lot of fun running into people we know and other people who live near us in New Jersey, etc., but I guess it could be annoying to people who aren't from New Jersey.
Why would anyone want to live anywhere except New Jersey? How could we possibly annoy people from other states? We are the most charming, fun-loving, cute and adorable people in the world (with the best senses of humor, hehe)!!!!!
