Hello everyone, I need help! I recently got in contact with a venue FH and I are really interested in, to do a tour and ask questions. The owner of the venue told me that they would be having an open house on April 1st from 12-4. I've never been to an open house, so I'm wondering if we need to be there at 12 or is it okay to show up after 12? And also do we need to stay all 4 hours? Help! please and thank you
