Went with a friend last night (10/18). We bought the Happy Haunting Hour for $25 plus fees online. Parked at 6:30 and was at the front gate by 6:45. I had read opening ceremony was at 6:30 so we thought we missed it, but they didn't do anything until right at 7.
Overall, we had a really good time. It wasn't very crowded (I think the weather had a role in that as it drizzled the entire time). What was really cool for me is there is a level of interaction and personal experience that just isn't possible at a massive event like HHN. We did each house more than once and it was cool to have the scareactors recognize us and interact with us like they knew us. Since their break area was all the way in the back of the event, house scareactors were constantly walking through the streets. They'd stop and talk to us still in character, almost like a continuation of how they talked and interacted with us while in the house. That aspect was really cool as I felt like I was part of their story in a way.
We also got lucky with the secret bar. One of the street entertainers came up to me randomly and asked if I had heard of it. When I pointed in the right direction, he handed me a coin and gave a clue on where to go. That was a nice surprise.
I really hope this even does well here. I have been following Dark Harbor for a few years and I was excited when I heard the company was coming to Orlando. While this year was good, I know they will take lessons learned from this year and next year will be better. It's worth checking out for sure.
