AHS, Exorcist, and WD are the 3 that build a big line fast. Originals build a line slowly and become walk on by the last hour. TCSM hasn't been as busy as I have been expecting for a house that is located there, I think Chance does a good job a shielding it from B&T release. If you chose to do Chance don't wait 75 mins for it. Make sure you hit it up right after a B&T started for a minimal wait as it will yo-yo.
Also for this Friday and Saturday, and YMMV, with the AP event they block access to the tents until 6:30. However if you have an AP but didnt sign up, if you wander over there some time between 6:00 and 6:30 they will let you though, at least they did that for us on Friday. This allows you to do a SS house or two and still beat the crowd to the tents. But that will only work this FRI and SAT.
Also NY S&S seems to let you into both WD and exorcist. However it seems like WD has either opened later or just been delayed the days I was there. Saturday did Exorcist and got out and WD still wasnt open but had a 30 min looking line built up.
The best advice for people once the AP events are done is to S&S in either NY or Hello Kitty and do either Exorcist or AHS then go to the tents and go in order from H2 though to Chance. That process should allow you to get though 5 houses by 7:30-8:30ish depending on crowds. If you get greedy up front and try to do 2 SS houses you will get stuck behind the front gate as they go to the tents. But after the 5 houses early do zones and shows and then you have to suck it up and either wait in line for WD or the house u didnt S&S early (AHS or Exorcist). After you wait in the one line you can wait til later for Ghost Town to slow up and then hit the other IP house right at the buzzer to wrap up.
