Kevod Horav. It is very common that during the Yom Tov of Sukos family and friend visit and eat together in the Suka. Since there are different traditions as to eating during Shemini Atzeres in the Suka, what should be done when the host maintains one tradition and the guest or a son-in-law keeps another?

Indeed, the difference in Halacha traditions are most important, and one should avoid being invited by a host that follows different minhagim. When that is not possible, as in the case of a son-in-law or similar, the main concern should be to maintain peace and Sholom Bais. Also the respect to the father-in-law or host is essential and a correct plan should be arranged before the Seuda begins. Horav Shlomo Miller’s Shlit’a opinion (following his tradition) is that one should keep what is written in the Shulchan Aruch.
