Our kids are mostly married but B”H our table on Shabbos will usually have up to 20+.
Many years ago we invested in several sets of nice yet inexpensive stoneware; silverware and stemware. In the long run it comes out cheaper that having nice paper plates, etc. We have enough that washing is not necessary until after Shabbos when we do several loads in the dishwasher. It does enhance the Kavode Shabbos and our Oneg Shabbos.
