I heard a story last week about a couple with: two engagement parties, three showers, three golf get-togethers, a "dress reveal," a bridesmaid luncheon, bachelor and bachelorette parties, rehearsal and dinner, morning-of brunch, next-day present opening, and maybe an evening-after dinner. All of them mandatory for the bridesmaids or groomsmen. (Oh, and a wedding somewhere in there, too.)
Many couples can end up putting a pretty big dent in the social schedules of their nearest and dearest, even if they didn't mean to, but I think this case is a tad extreme -- especially expecting the bridal party to show up for all of them.
The wedding is actually the only required event. The rehearsal is a good idea, of course, but even it's optional. Showers, golf games? Great if it works out, but not a big deal if someone can't make it.
How many events will your attendants be invited to? And how many do you think they'll be able to attend?
