I wouldn't be so sure of this. The more I read the more I believe they will be there the week of Dec. 8-14.
Pop Warner does typically go the first full week of December. However being that the first weekend is part of the holiday weekend (which does not typically coincide with the first weekend in December), I believe that this will not hold true for several reasons...Number one, the calendar year for November/December 2013 exactly mirrors the calendar year for 2002 (Thanksgiving on Nov. 28) so I looked at historical Pop Warner dates for 2002 and their dates for that year were Dec. 8 - 14. Second, I saw someone else said that they always have some big competition Thanksgiving weekend also, so there is little chance they would travel that weekend. Also, Disney is very crowded that weekend following Thanksgiving usually, so I can't imagine Disney would agree to discount block rooms for Pop Warner during a high-crowd time period like that, as it would be actually a money losing thing for them. Pop Warner always takes place during a slow week for Disney.
Hope that information helps someone...it's still good to be flexible because you never know for SURE until the dates are in black & white, but my deductive reasoning skills tell me that it's a safe bet Pop Warner week for 2013 will be Dec 8 - 14.
