It could be "Jersey Week" - to quote Mouseavers...Usually the first or second week of November. The New Jersey schools have a teachers' convention (2009 dates: November 5-6), which is often close to Veterans Day. Lots of people take advantage of this time off to pull their kids out of school for the whole week and add on the weekend before and/or after, taking this opportunity to go to Disney World in the "off season." New Jersey is the single biggest market for Walt Disney World -- you do the math!
We've hit Jersey week before and it wasn't all that bad, especially compared to Thanksgiving!
