Spa Day!

My Daughter, Amber, is playing hooky with mommy today (she wet her hair last night without me knowing & went to bed. When I saw her this morning I was shocked. All I could do was laugh, afro city...so we're having a "spa day" hair, nails, facials, movies & music... my other children were a little jealous. (I'll make it up to them this weekend) Are there any recommendations for great spa facilities in Philadelphia? Please share your experience with us.
