Halacha is plain and clear about shabbos + yom tov, we do not say sholom aleichem nor eishes chayil.
A further sign that I am going to hell in the afterlife. I have very distinct memories of singing Shalom Alichem and Eishes Chayil in the sukkah on Yom Tov. I guess if I violate a halacha that is a plain and clear as that, who knows what else I’ll violate.
I would venture to guess that this violation of halacha ranks right up there with idolatry, blasphemy and murder.
