We are having the same concerns, and I am stressing way too early about it too!
I did look up historical dates for Pop Warner, and in 2002 the calendar was exactly the same as in 2013 for November/December. Thanksgiving was on the 28th, and Pop Warner in 2002 was Dec 8-14. SO...my plan/hope is to go the week between Thanksgiving & Pop Warner - Nov 30 - Dec 7.
BUT...that being said I did read on **************.net that they are anticipating Pop Warner to be that first week of December (but it says "always first week of December" which, according to my research isn't accurate really). I am not sure if they are just guessing or have true knowledge of this...as I have tried everything I could think of and can't find the actual dates this far in advance anywhere. My best guess was to look at the historical dates.
SO, with a wish and a prayer and hopefully some pixie dust

we are PLANNING right now on being there the first week of December - but being flexible if need be and may change once the Pop Warner dates are released (not because of crowds really because we've been there during PW before, but because we are staying onsite this time and would LIKE our best chance at a possible free dining or discount, which wouldn't happen PW week).
Good luck in planning!! I am already WAY too excited!
