I’ll tell you what… why don’t you show me a source that says that having a non-Jew over for Yom Tov where there is no cooking is assur?
Do you even know the reason why it’s a problem on Yom Tov and not Shabbos? The reason is SOLELY because of the cooking!
And, for the third time, I’m not advising anyone to follow what I do. I clearly told everyone and anyone to contact their own LOR.
