At the Haunted Forest Of Carousel
We actually do it by section, for placement purposes the Haunted Forest is divided into four sections and we do constant walk behinds following patrons. We announce the runner up section and the section of the night the next day right before the show. The Section of the night has been one of our best actor incentive we ever came up with. They often shout they're section before going back "Section 2" or "Section 4" and they all get fired up to win. Sometimes it's so hard to pick the best section that we have an occasional tie once or twice each season but it's definitely a motivator besides just telling the actors you need to be more scary. The sections that come in last we usually talk to the individual person or persons that are not doing the best and coach them in private. Most of the time it works. If it doesn't and they don't respond well to constructive criticism we just let the actor go. We have no shortage of people who want to act at our place. At the end of the season we also do the award system with Actor of the year, Rookie actor of the Year, Most improved etc.
