DOES ONE DO MELAVA MALKA AT ALL THIS SHABBOS PESACH?
For Chutz La-Aretz, there is no distinct melaveh le’malka meal, because the Yom Tov meal takes its place.
When Shabbos moves into Yom Tov (Chol Ha’Moed) one has a melaveh le’malka meal, which both accompanies Shabbos at its departure and honors the continuing Regel.
See sources on this matter in Chazon Ovadya, Shabbos Vol. 2, Seudah Reviis 4.
