I've read about this here probably 50 times at least, and still, I was SHOCKED when she suggested this. Our ceremony is starting at 12. She told me I should put 11:30AM on the invite, to "encourage guests to get here in case of traffic and who may not be familiar with the area." She even went on the say that guests will appreciate the extra time to "relax, use the restrooms and explore the grounds."
I come from a family that is always early to everything. When we had family parties, my grandma would should up one hour early. Now, imagine my relatives all showing up at 11:10AM, thinking the ceremony starts at 11:30. What if I'm running 10 minutes behind? I've then had my guests sitting around waiting for an HOUR! That's fucking crazy. And rude. And obnoxious!
And I really liked this coordinator until she suggested this. ugh.
