NJ week is so named because NJ schools are closed on Thur and Frid for teacher conferences. Some also close 1/2 day or full day on Weds. And still others also close Tues. for Election day. End result - many families take the week off since the kids miss at most 3 days of school. Of course, WDW is the most popular destination. Since the other 49 states are still in school, its a great time to go crowdwise.
