Your big day is for making memories, not stress.
Even if you are organized, you should not manage your own day.
Gift yourself the freedom to enjoy it without keeping tabs on the itinerary and logistics.
Know who else shouldn't have to manage the day?
Your mom. Your MOH. Your sister, your friend, or your aunt.
They should be enjoying the day with YOU. Many venues strongly suggest (or even require) that you hire a Coordinator for the day of your wedding.
Let a team of professionals step in and manage your wedding day while you focus on making memories.
