This group is average aged of around 35 . They will kick out anyone in the group who doesnot abide by their simple, totally logical rules.
Two were ejected when they began swearing and using racial slurs to attempt to make "something" happen. They ruined the entire night , all films and recordings were deemed unfit to keep let alone show on their web site or be shown to the current property owner.
When we would host a Ghost-Seekers Night here I would suggest that only small groups of people should inhabit the wine cellar at a time. Sound echoes down there and it is Very hard to maintain anything like "Quiet" with more than just maybe 4 or 5 people in the room.
A large group of serious /adult acting people would be alright.
Most groups of ten or more usually commonly will be talking, mumbling, laughing, farting(which creates more laughing..)
Too much terribly gross farting creates stained clothing, nasil irritation and possibly alfactory death.
