Ill give you a room that Tony Cooke came up with and we did 10 years ago. The Gift Shop
Regular room, not scary, normal florescent lighting.
Patrons come in and there is a lady there to take their glasses. Hang your t shirts and such up for ombiance. Sign and your lady say to sign the guest book for a free drink. When the first one heads for the refrigerator out pops your character from it. In your case I see a jester with a ski saw, but then I've never seen your haunt so that detail can be suit to fit. THIS ROOM WORKED AWSOME!
