We are having an outdoor wedding next fall. We are renting a tent, tables, and chairs. But we are thinking of just doing heavy hors d'oeuvres instead of dinner. I would love to get some high top tables with bar stools to mix along with regular tables. But my question is, will the chairs sink into the grass when people sit on them or do they put something on the ground under the table/chairs? If not does anyone have any suggestions? TIA!
