Thanks for the suggestions, Rebecca! I do have goals set for the event and will definitely think of ways to "slow down" the brides. It's been YEARS since I attended a bridal show for myself, so I forgot how hurried the brides are at these events.
If you're at all interested in bridal events near Dayton, the same company that produces the Columbus show also holds them in Dayton. I've only heard positive things about them and they have been very professional and helpful to work with. It's Claiborne Productions:
