Here's the perfect storm: cocktail party on Wednesday night, I have a few dozen frozen latkes in my freezer that I made yesterday and two big balls of cookie dough to cut out and bake before guests arrive (they'll be able to decorate cookies at the party). I was planning on doing all the rest of the prep (making a last hors d'oeuvres or two, baking the cookies, setting up, etc.) the afternoon before the party, because I have a final exam that morning and will be studying until then. Now my building has just told me they're shutting off the water from 9-5. No dishes washing, no running water at all. Guests arrive at 8. Aside from filling up every container I have beforehand, any advise? Unfortunately I have to focus on my test today and tomorrow so can't do much prep ahead of time.
