I haven't got anything set in stone, yet. If jalabert's schedule works out, I'd really like to spend the first part of the trip tooling around the area in some place we haven't yet visited. So far, this is what I see:

Arrive Oct. 25/26: date depends on jalabert's schedule
Oct. 27 - Nov. 1: No solid plans. I'd like to go to the Halloween Parade again but if there's something cool to do elsewhere, I'll change my plans.
Nov. 2 - Nov. 4: Con
Fly out Nov. 5/6: I usually fly out on Mondays since museums are closed and people are normally back at work.

I'm definitely of the opinion that we should go to museums on work days. I try to find non-museum things to do on weekends because I hate crowds.
