I haven't been to a ton of weddings before, and I cannot remember how exactly the ushering works. We are having about 150 people at our wedding and would like to reserve the first 2 or 3 rows for close family, but other than that we didn't want to designate where people sit (no "bride side" and "groom side"). How would the ushering work in this case? If we have our ushers just escort people to the next available row, will that result in the first 2 or 3 seats of each row being occupied, but nothing else? Will people scoot down the row they are seated to in order to make room for more people? Sorry for the stupid question, I'm just trying to picture how this will work!
