Save your money!
The good: you can buy the VIP package which allows you to jump the long queue to get into the manor.
There were a few decent rooms and 1 awesome one toward the end. Other than that it wasn't very impressive. You were pretty much push through like a pack of cattle because they were trying to get so many people through.
The bad: in one area your feet and pants get wet. It's the middle of October not mid July!
We paid more to 'shoot zombies with paintballs'...well let's just say it was pretty elementary. Pump shotgun type guns that shoot about 10 feet and hold maybe 6-8 shots. Half way thru you get a new gun for the second stage of the mission. Same type of gun and same concept.
We waited over 2 hours for this and it totally wasn't worth it.
Overall save your money, I wouldn't recommend it to anyone. Best part was the VIP line and the very last room in the mansion.
