I just returned from an informative seminar about YOU! The bride-to-be. It gave some insights I felt worth sharing: In the Midwest, we have larger reception invitees than on the coasts or in large cities. By about 100 guests! 120 vs 220. The average engagement-to-wedding is 14 months. What is the first thing a bride-to-be reserves? A venue. 80% of couples are making wedding plans by their mobile phones.
