This is so funny! Back in September or October, I posed a very similar question. I asked if we should go late Sept/early Oct or late Nov/early Dec...and the majority of the responses were for Nov/Dec.
Granted, you are talking a couple weeks after what we were inquiring about, but still pretty close.
One of the primary reasons for our post-Thanksgiving trip decision is so we can see the holiday decorations. And one of the main reasons everyone gave for avoiding early October was the bug issue. Can't remember what they are called now, but apparently they are quite remarkable at that time of year.
Have fun planning, no matter what you decide.
