Mark the calender. Opening night for Potters House of Horrors is October 16th to 31st 2009! Opening at 6pm and running to 10pm nightly. “Family Hour” will be back again between 6 and 7pm. Family hour was introduced for 2008 to try and accommodate the squeamish or younger audience. Its a tamer version of the show, more or less static display, no actors or animations. Best part is the Family Hour Tickets are at a reduced Price! After 7pm all the beasts come out for the full production.
