We did this one night about 8 years ago at our haunt. Some groups were very scared and freaked out while some groups figured it out. It was fun, but labor intensive and really not worth the trouble. The customer complaints were pretty intense.
That year we had a volunteer group each night to supplement our acting staff. One night it was a sorority house with 7 college girls (19 Ė 21 year olds). We had been wanting to try this, but didnít want to give up a good actor. So we decided to try it with this group of young girls. A girl would approach our starter at the front of the cue line and ask where her friends were. The starter would tell her the group already gone in. She would say she was in the bathroom and complain that she didnít want to go through alone. The starter would ask the next group if she could go through with them. Of course the groups always said yes and so our victim would introduce herself to the group and then enter with them.
About 12 scenes into the haunt; two of our clowns would grab her and drag her kicking and screaming away from the group. Then she would go back to the entrance and wait her turn to approach the starter for the next group.
Some of the extreme reactions; people would try to rescue her from the clowns and get very upset. Even had a woman call 911 to report the kidnapping. One guy became very attached to the girl in his group and he stood there in the scene crying. Some people complained at the end that a person in their group had been touched and taken away. Some people would scream and run away and some people just kept going through the haunt without concern about her safety.
You couldnít insert someone with every group, we had to wait at least about 5 or 6 groups and we tried to pick a group that looked the most susceptible. We had a DJ next to the cue line to keep people entertained and distracted so groups further back in line werenít aware we were inserting anyone. We never put her in with a family with children.
At the end of the night we decided not to do this again. The scares were pretty good, but the customer complaints and negative comments outweighed them.
