Nope, that's only if you're gonna do Stay and Scream. If he's going to enter from the gates, he needs to go the opposite way. I'd actually recommend arriving around 5 PM, as insane as that sounds - security has been nuts this year, with waits of over an hour reported at opening. Be there early and be ready. They've consistently opened the park gates themselves around 6 PM. If you show up at 6, you will wait at least half an hour or more to get through the security mess.
Once inside, hang right to do House of Horrors immediately. I'd actually recommend hitting Alice Cooper right after due to how the lines are set up. The House of Horrors exit will have you pop out right next to Cooper, and the Cooper exit will have you pop out right next to Penn & Teller. You can probably get right into Alice Cooper by the time you just walked from the House of Horrors exit to P/T.
Walking Dead, by this point, will likely have amassed maybe a 20 minute wait... go ahead and just wait it out. Everything else is up to your judgement. Silent Hill almost always drops to 15 minutes or so in the last hour the event is open since it's usually the first house everyone hits. Gothic & Dead End will likely drop to 30 minutes later in the night... you may just need to stick it out for one or the other. Do keep in mind that most people consider them the best houses of the event this year.
