A: In an ideal world, the groom has a firm handle on all wedding-related details and tells the best man (once), the best man then tells the groomsmen (once), and all males arrive at every appointment on time. In reality, most grooms need the bride to issue them a reminder (or three) about the various wedding events and tasks. The good news is that, in the end, the guys always step up. The groomsmen, too, might surprise you by being totally on top of things. And there's no question they won't miss a minute of the bachelor party.
