Oh, and, if you want a quiet getaway with some Activities nearby, the wine region is always good and there are probably lots of bed and breakfast type places. I bet it's "interesting" getting a booking for a long weekend on such short notice, but then, I don't think it's the busy season there yet.

The retreat idea is great, but I don't know anything about those sorts of places. You could create your own at home, though -- order in, go to the spa for a mani/pedi and maybe a facial or silly wrap or something you wouldn't normally get?
