I know the typical ways to talk with guests are table visits and receiving lines, and sometimes releasing your guests from the ceremony - however I'm not sure any of those are exactly what we're looking to do.
FH doesn't want to do table visits since our plated meal will be served all at the same time (within a very short window) so it's not like we will have our food first and then our guests will. Receiving lines seem to take a long time, and we want to go immediately from ceremony to cocktail hour without people standing/waiting around for us/each other. And our venue has a little different seating so it's not easy to release rows by walking up the middle aisle.
Any other ideas you have on how we can best talk with our guests and make sure we don't miss anyone?
