[Avodah] Ushpizin and Sheva Berakhos

[Chaim G Steinmetz]

I see no one answered with sources, therefore:
In the sefer Nisuin Kehilchosom (14:76) he brings varying opinions, some
hold that Chol Hamoed is considered PC (Yefa Levav), and some disagree
(Zchor LeAvrohom, Betzel Hachochmoh and Sovah Semochos).
There is a specific discussion in regards to CH Sukkos that each
particular day should be considered PH (Avodas Yisroel (from maggid of
Koznitz),  Meishiv Halocho), but others disagree - see at length Betzel
Hachochmah v 2:1.
