Signing in for your tour at the CAC? Remember – the one-hour rule is in effect. Please do not sign in more than one hour ahead of your tour time. When two docents are assigned, the docent who signs in first has the choice in giving the tour when there are not 10 guests. With our busy season coming up, more than one docent will often be assigned to a tour. Depending on the number of guests who arrive, the one-hour rule helps to ensure fairness in determining who will give the tour.
