We were originally planning on a plated dinner but now that our guest list has grown significantly we are probably looking at switching to a buffet to cut costs. If you're doing a buffet, how do you plan on releasing tables? We are doing open seating so won't have table numbers which would seem most logical to me. We would like our seniors and little kids to get food first but don't know the best way to convey this. Any thoughts would be helpful, thanks.
