Purchased my tickets (2 of them) from their website for me and a friend and redeemed them at the place, hassle free. We got there at about 7:15-7:55pm or so (don't remember exactly) but there was already a line building up out front. They had a line for the fast pass people and a line for general admission which of course was the longest line and what I had purchased online. They had security (MCSO- Sheriffs) everywhere, I felt really safe despite the fact we were just about to go through a scarefest.
We waited in line for what seemed like 20-30 minutes which wasn't that bad considering they did have at least one or two live actors out front scaring unsuspecting people in the parking lot and in the line itself. Once we made it to the front of the line me and my buddy were merged into a group of other people to be sent into the starting building (this is why it would be good for groups of say 5-9 people who know eachother).
The first building you go through which is the main building is the best building out of the bunch and it was very exciting or horrifying depending on how you feel about jumpscares (the girls who were merged into our group were scared pretty much every turn). It's like a really well built maze that you follow in the first building which seems endless but I thought it was awesome. The other two weren't that great, one sort of felt like it was thrown together to lead to the ending which felt even smaller and inadequate compared to the starting building.
TL;DR: It was a great experience for the price. The only thing I didn't really care for was they were pitching the fact it was "3 scary attractions" when in reality it was 1 good one and 2 inadequate ones thrown together but I would still do it all over again because the first building/attraction was awesome. I will probably come back next year to check it out again.
