I went to this over the weekend -- my media friend had an extra pass and he let me tag along. Honestly, it was a lot of fun.
It's not Dark Harbor at all -- if you're hoping for/expecting that kind of event, you'll be disappointed. It has the atmosphere of a block party or a small town fair, especially before 8pm, which is the family-friendly portion. There are carnival rides and carnival food, and the "trails" as they're called have people in them handing out candy instead of scare actors. After 8pm, the scare actors come out -- they do a bit where Shaq comes on a screen and does a spiel about the ghosts of the Queen Mary coming to life, and there's a little chainsaw performance followed by this cool marching band that walks around.
At that point it starts to feel a little like the old Dark Harbor event, but it definitely maintains the "block party" vibe all night, which again I really liked. Idk, maybe it's because my drinks were free but it was super fun. Definitely hokey in parts but in a way that feels intentional, like they're kinda winking at you -- one of the trails has a section called "The Pumpkin Shaq," that kinda humor.
And honestly when the scare actors come out, the trails are pretty good. They're short, but immersive and well-designed. One has a bar in it, like Dark Harbor used to do. This is a 13th Floor event, so they use a lot of the animatronics you see at Haunted Hayride, which can be hit or miss, but the actors were consistently good.
I'd rank the trails as such (Shipwreck Graveyard is essentially a scare zone):
1. Diesel's Pumpkin Patch
2. Dead Man's Wharf
3. Pirate's Cove
4. Lost City Boardwalk
5. Midway Madness
So yeah, all in all it's a fun time. If you're looking to go to a Halloween party that has the added benefit of also being a pretty decent haunt event, this is it.
