From 9 am to noon, Monday thru Friday, except major holidays would probably be the best time to get a tour. The Posse is open from 9-3, but in the afternoon there might not be someone available to give a tour. I took my grandsons there in February. They not only got a tour but they were made an honorary Posse Person and given a badge. BTW. Everyone. If you do visit the Sun City Posse, bring a badge from where you live and you will be given a Posse badge. I'm talking about the kind that is sewn on a uniform. My grandsons had fun looking for the badges I brought back from a visit to them in South Carolina. Did I mention that the badges are displayed inside the Posse building in glassfronted cases along the walls.
