Was able to clear out 5 houses by 7:00 last Sunday from NY S&S (ST4-Exorcist-Yeti-Bloodmoon-Chucky) and 5 houses by 7:30 last night from Central (Monsters-Oddfellow-Deal-Chucky-Bloodmoon).
Starting to think the play might be NY S&S to ropedrop ST4 and then gauge Exorcist (come back later if it's too long). Then go directly to Dragons, Yeti, Chucky, and Bloodmoon in quick succession, and check Monsters afterwards. While I've been noticing that most people start to come in around 8:00, you may be able to get 5-7 houses done by then depending on the initial crowd level that night. At that point, I'd suggest doing whatever until 12:00 then catching the rest, unless you'd rather just eek it out and wait in the remaining lines.
Will suggest this though: Bring an umbrella, bring a (cooling) towel, stay hydrated, and grab a snack if you'd like beforehand.
