^We've been the same way: used to do thanksgiving week, now go sometime in December, usually the week after thanksgiving. Honestly, it's a crap shoot. It's still so busy sometimes that it's hard to do everything. The weather is what it all comes down to, but even if it's cold there's still a ton of people that come out. Sunday evenings and Mondays are usually good though, those are the best days you can plan around.
