1. Arranging the florist's delivery.
Photographs of the bridal party shouldn't happen before bouquets and boutonnieres are ready! Have your florist's delivery time be arranged for an hour before the photographer's arrival. They need to be there on time for the photographer to start pictures!
2. Coordinating payment for all vendors.
The last thing you want is to get several emails from vendors on your honeymoon! Arrange your payments before the wedding, or have a designated person to settle all the "bills" the day of the wedding!
3. Having a strong enough timeline!
This should be done in advance, and if it is overlooked, it can cause major stress on the wedding day. Your wedding day shouldn't be full of any stress, so planning in advance with a strong timeline will help when unexpected things happen on the wedding day.
Having a strong timeline includes: cushion time between major events, details of vendor arrivals, bridal party arrivals, details of every hour from set up to tear down.
