I always heard that the weekend after thanksgiving (not black Friday - the following weekend) was the best time. We went then in 2007 and vowed to never go any other time based on the small crowds. We have gone twice since in the summer due to our kids being in school and not wanting to take them out for a good long trip. Would love to go back after thanksgiving, it was a great way to kick off the Christmas season for us with all of the decorations in place as well as the Very Merry Chrismas Party.
My neighbor went during "Jersey Week" and thought that the crowds were small, with a majority of the people that they talked to being from NJ as we are. Seems like NJ is the only set of school districts with any sort of break during that week so the Disney crowds were still lower than most times of the year. That is why I would say the week I stated above would be better, no state in the country has any breaks then. The Texas break is over and everyone, including colleges are finishing up before the Christmas Holiday break.
