I was there Saturday night. We did not get the Express pass, and probably should have... we didn't get around to all the mazes. Arrived at 8pm, and left around 11:30.
We did Blackout first. Great concept, but since I was in the back of the line, I hardly saw anything at all. Probably a lot better if you're towards the front. They were screaming a lot, and I was more like, "What? What happened?" I think I even accidentally stepped on the foot of one of the talent, I felt bad about that. There is some minimal blue lighting along the floor, enough to make out vauge silhouettes. As warned, the queue line moved pretty slow. We were just past the Looney Tunes tree, and it was about a 30-40 minute wait. We saw the line get longer, all the way up to the Golden Bear stage, later that night. Thought would probably be at least an hour.
Went to Willoughby's next. The line was not only insanely long, ending just short of the old Dragon Inn, but it moved extremely slowly. Even slower than Blackout. I believe it ended up being a 90 minute wait. The sets were great, we were very impressed, although it does feel very "open" rather than claustrophobic. The talent seemed enthusiastic. We saw most of the scares happen to a couple in front of us, though, so we didn't get too scared ourselves. And even thought the line moved slow, it did minimize the "conga line" problem so many other large parks (HHN) have, as each group did have about a 10-20 second separation.
By the time we did those two mazes, it was now 10:30. But the good news: the line for Black Widow was non-existent. The maze is only okay, are there aren't many hiding places for the talent, but they seemed enthusiastic. Two frat type guys in front of us were getting scared at a lot of the stuff, and we were noticing the security people in the maze were laughing at them. Which we actually thought was pretty cool, oddly enough.
As we walked the long way around the park, the line for Cursed was also essentially a walk on. In past years, for some odd reason, I always find myself startled by the talent in this maze, even though the themeing is basically just netting. Maybe it was because of the couple in front of us got all the scares, but I didn't get startled once this time. There also seem to be a disproportionate number of monsters on the right side than the left.
Finally, as we finished looping around, the line for Slaughterhouse was also minimal. The wait took a bit longer than expected, due to a very well-meaning and enthusiastic employee giving a very long, passionate, character driven safety spiel. His heart was definitely in the right place, but it made the line take much longer than it should have. In any case, I liked this one last year. It's completely unchanged as far as I can tell, but for some reason, it just seemed a bit "off" this year. Perhaps it was just bad timing with some of the talent, although I did get a few good scares regardless.
By that time, it was late, and we were too tired to do or see anything else. I really wanted to see Aftermath, as I've not had a chance to do that one at all yet, but there was still sort of a considerable line for it when we walked past it at about 10:45 or so.
In sum: lines for what I'm assuming are the "good" mazes (Willoughby's, Blackout, Aftermath) will be long all night. Lines for all the other mazes will shorten considerably after 10 or 10:30pm or so (even though we didn't go on it, the line for Joker's looked like a walk on just before we left the park). But the lines for those three are so long and slow, it would probably be worth getting the Express pass.
Yes, they are giving out the number tickets. Although on our very first maze, Blackout, we didn't know this, and we were never given a ticket. But the guard just let us through anyway with a shrug. Not sure how much they're really going to be checking this or not. We weren't trying to cheat the system, but we easily could have, I suppose. For the record, we were given one for all the other mazes, even the walk ons, which seemed rather pointless. But better to have the extra security than not, I suppose.
One note on security... it was quite good. I didn't see anything get out of hand except for one incident, and it was handled quickly. A group of teens in front of us had a green laser pointer while in line for Willoughby's. They were aiming at buildings, Tatsu, and all the way up and down the Skytower. And no lie, within 30 seconds of them aiming it around, a security guard came up to them and confiscated it from them. Awesome.
