In my culture, the bride and groom have to address every table to thank guests for their presence during the reception. The thing is, we're a little tight on time because we have to be out of the reception hall by a certain hour. I'm concerned that, since we have to address at least 22 tables, my groom and I will have no time to eat, dance, and otherwise enjoy our reception.
For those w/ experience regarding this custom, how long does it generally take to address each table? What should I expect?
