I did the Big Brother house tour 2 years ago in 2012 after the house had closed and was open to dreamworld public in the holidays.. The lady who was giving my tour.. had NO prior knowledge of the shows former existence or any real insider info to the show..
She was just another dreamworld employee.. coming in to do her scripted, tour job of what she knew at that time.
As a huge fan.. I had great delight in telling her and my group, all of the info that I knew and had experienced over the years and was disappointed that they knew nothing.. other than to get us from point a. to point b. so we could get out housemate photo taken in time
