Is there a point in going to mikveh erev shabbos for kovod regel if meshamesh Laila shabbos erev Shavuot
Answer:
Immersing in the mikvah erev Shabbos certainly has a point as one adds more purity and holiness to himself in preperation for Shabbos. Once one becomes a Baal Keri before Yom Tov the tevila of Erev Shabbos will no longer provide added purity for Yom Tov.
