All day beauty spa in Nurnberg or Kaiserslautern Germany?

Im thinking of a birthday gift for a special lady and I figure an all day spa would be nice please help sombody

Dude, Nurenberg, without any doubts, it's bigger and a lot more history than Keiserslautern. I'd tottaly pick Nurenberg

The only reference I can find to an actual Spa is something about the "wellness centre" in the downtown area. The info is below:

Schulte's Hotel du Vin - Hotel & Boarding House Kaiserslautern:

Malzstrasse 7

Five walking minutes from the hotel is the Wellness Centre Kaiserslautern which offers wellness at its best on 5 floors. Additionally, the hotel provides a conference room of 40 m² with daylight.

I wish I could find more, but am limited by location! (as in I am in NC, and you are asking about Germany!!!!) Good luck!
