That’s a great question, Jera! Due to the contract for the venue and their availability, whether you advertise it or not, there will likely be an attendance cap. With 70 churches in your district, I suspect you’ll need a MUCH larger venue. One of the large churches (about 800 weekly attendance) I’ve served in usually had over 100 women attend our retreats. Would it be possible to survey the 70 churches to get a feel for how many may attend? Obviously, the date, cost, location, and speaker will help drive up or down your attendance, but even so, I’d definitely plan for more than 1-2 people per church to attend. Whatever you decide, make sure it’s crystal clear that there is a limit on space and that they need to register asap. I hope that helps!
