People would come to us later cause they knew other haunts around us closed earlier. We close around 12-12:30 every night. But I think it really depends on how you market it. You can say from 11-12 its the Xtreme Scream hour or lights out. I worked at a bar that stayed open until 4am. All bars in the area closed at 3am so people would show up for that power hour and the bar would be packed because they knew we stayed open. BUT... Like larry said the later you stay open the crazier the people are. BTW that bar burnt down so .... yeah.... Use your best judgment.
Best of luck to you and your season!
