I did not even spend much time here, because I was alone and my suggestion is to bring a friend along. This is a creepy place. If you have a headset, turn up the volume...really creepy sounds.
You will get very wet before you can enter the house...bring an umbrella, which may also be used to hit the creepy monsters away.
Here is one of the rooms, but there is plenty more to see.
