According to Chazal, only Yom Kippur may* supplant Shabbat.  For years I've been saying that the reason the Shabbat before Passover is called Shabbat HaGadol (The Great Sabbath) is to remind us of this.  Shabbat is greater than Passover, certainly greater than Passover cleaning.  Even if you love to clean for Pesach, and I admit that I don't, you shouldn't let Passover preparations turn Shabbat into something cheap and trashy.

Creative pre-Pesach cooking can be extra delicious.  My daughter reminded me that we can have kitniyot Friday night.  Kosher l'Pesach rice can served for Shabbat, postponing "What, potatoes again?" complaints.

Decorate with gorgeous flowers.  Make sure the house looks and feels Shabbosdik.

When the Moshiach comes, it will be Shabbat all the time, and we won't have to line our closets!

Shabbat Shalom U'Mevorach, May You Have a Peaceful and Blessed Sabbath
