We are having a ceremony at a park that is right on the water. For this we are renting white chairs. We have ALOT Of guests, around 175 or so Im thinking (after RSVPS) so my question is, is it neccessary to have chairs for every single guest, or can we just have a couple of rows in the front for like immediate family and then standing room? It is a VERY short ceremony, like 10-15 mins tops. What do you think?
