Weighted disposables and unbreakable glassware. Real china and glass in an open-sided room with uneven ground is a gamble, and lightweight paper plates move in the wind. Heavy plastic plates and stemless glasses look the part and stay where you put them.
Look up. If your sukkah is heavily decorated with greenery and vines, a nature table continues it and a formal one competes with it. If your walls are artwork and posters, the elegant palette gives the table its own presence. Either works; mixing both palettes on one table rarely does.
Tablecloth clips at every corner, weighted or heavier plates, stemless glasses, and napkins tucked under a plate rather than fanned on top. On a genuinely windy night, a runner with placemats survives better than a full cloth.
Most families set a fuller table for the Yom Tov meals and something simpler for Chol Hamoed, which is also where the disposables earn their place — you are setting the table many times over a week, not once. Buying a bundle for the main meals and basics for the rest is the usual approach.
