Quick overview of my impressions from yesterday... We missed saw due to nothing being "new".
Cabin was my favourite. Different routes, and seemed to be literally bursting with actors. In one room there were 6 actors running around the room, in comparison to the three of us. Being continually matched on numbers with actors:guest ratios worked really well - you never knew where to look! They all seemed to know how to use the space they were using, they may have been getting very close with an "in your face" approach but I think that worked well in here. On a re-ride (if you could call it that) after the fourth door's scare the doors accidentally closed again, and re-locked us from going anywhere. The people in my group were desperate to go but with me at the front I couldn't do anything and they simply didn't understand the doors physically locked! We passed the control room but went elsewhere - where does the spinning doll door go? Two groups tried to get in but it was locked on both occasions. I do agree that theming levels drop mid-maze, the moment after you've left the "cabin" and have entered the lab though.
Asylum indeed seemed longer than normal - still very enjoyable. The only part I was genuinely "frightened" though was the suspense at the final corridor with the curtains however.
My bloody valentine was, in my opinion, terrible. Theming inside, even compared to the second section of cabin, looked poor. Very few actors actually -inside- the maze, and those that were didn't seem to be doing much. Even with nobody in front of us, they were just standing around swaying slightly, doing nothing when you passed.
Blair Witch Project was even worse - what seemed like the longest queue for any of the mazes that night (I wouldn't dare call it that) - was simply a literal walk through a long woodland path behind the buildings. A maximum of say, 5 of the actors who were there actually made themselves known. Toward the end one of them approached saying there was an "e-stop" and we had to go all the way back to restart. By this point in the walk most of the people simply wanted to leave, rather than walk up and down the entire strip again! Shout out to the phlegm-filled actor who was waiting with us back at the station to keep us entertained. In hindsight she was the most entertaining element of the entire "Blair Witch" experience.
Park was very quiet, but still managed to amass 30 minute+ queues for rides like stealth and nemesis, thanks to reducing them to only one train. Great stuff in the rain.
