With S&S you'll have no problem at all.
Do the 3 soundstage houses (CBT, Blood Ruins, Where evil Hides) as they open. These SHOULD be the first 3 houses that open for you. After that make sure you hit Terror Mines, Body Collectors, and the Skool because these 3 (well mainly The Skool and Body Collectors) seemed to have accumulated close to 2 hour waits last weekend. After that, hit Demon Cantina. It may have a wait, but it shouldnt be too bad, and after you hit it, you would have done all the houses, and I don't think it'll be all that late, so you'll have time to see the shows, ride the rides, and repeat the houses.
