On my last day of work before mat leave, H and I went out for a fancy dinner. It was so nice! I have good memories of that.
Of course Andy wasn't born for another 3 weeks. Bugger.
I love the spa day idea. Cut/color, mani/pedi and a prenatal massage if you can $$ swing it. What a treat! And you'll be grateful to be feeling pretty after the baby arrives. My girlfriend had packed me a shower bag of Aveda sample size toiletries to bring to the hospital, and I remember feeling like a million bucks sitting in my hospital bed, post shower, smelling pretty. So I enthusiastically support having hair and nails done too
