According to the manual, obtained by ABC News, security guards were instructed to show kids what should be brought into the house and what rules they would need to obey during their stay.
In the packet were instructions for when and what teens were allowed to drink, informing security to tell them that "the hard alcohol will be given back once we feel you have earned it." The manual also said that security should only allow clear alcohol to get into the hands of minors.
Breit said his group of friends initially booked two houses for the weekend through Hnetinka back in February, but they were moved into Sachs' house together just days before.
Breit said that all 98 teens staying at the after-prom had to find a way to leave Friday less than a day into their planned weekend stay.
"It was bad enough we didn't even get our money back," Breit said. "But losing it all after 12 hours. I don't think any kid was going to pay for another after-prom."
