A bit of a flying visit to this one on October 31, and it was a pleasant surprise.
In a nutshell: there was 4 mazes, the rides were all open, trick or treat stations, Halloween themed concessions, a show, face painting and scare actors throughout the park.
Halloscream is a separately ticketed event, and based on it's popularity I hope they add dates and expand the event next year.
The mazes:
Dead and Breakfast: this is a slightly re-themed Mystery Manor with a different narrative. It's short, but the sets are great and the scare actors were seriously going for it. A friend who was working in the maze promised she'd make me crap my pants, better luck next year lol (or slip some laxatives in my drink before the event). After years of Halloween Horror Nights and many other US haunts I'm pretty de-sensitised.
Private Screaming: located under the wild mouse in what is usually a function room I believe. This was another really cool maze with some great performances from the scare actors. You go into a screening room and sit down to see one of the scare actor's films, but something goes wrong and she bursts through the screen and complains you've ruined your movie and you should get out. What follows is various movie monster (human and otherwise) encounters. Norman Bates was especially good.
Alone: this is in the mirror maze under the slides in Coney Island. Basically it's in the dark with scare actors at various points and hanging bodies to navigate through. Good fun.
Madame Fortuna's Forgotten Funfair: a carnival themed maze in a tent on the old Ranger site. A lot of fun with really committed scare actors and even some rather acrobatic performances. Sets weren't anything too great, but the performers more than made up for it. Another fun maze.
It's a really solid event, and guests were dressed up even more than the scare actors in some cases, some really impressive costumes. My only regret is I didn't have more time to spend there. Crowds were light early and they opened about 15 mins before the advertised start time. I'll definitely go back next year if my schedule permits.
