Ideas for a 40th Birthday weekend golf trip ??

Looking for ideas on a weekend golf/spa break to celebrate my 40th. Its not till next year but want to start dreaming of (and saving for) a top class golf trip - somewhere I've not played, and will be a bit special.

It will be a trip for the missus, hence the spa bit.. (the celebrations with the boys is already in the bag)

Initial thoughts are Old Course Hotel, with a round on Old Course (hopefully) or Turnberry ( playing Ailsa)

I've been lucky enough to play all the Gleneagles tracks so I'm ruling that out.

Also giving some thought to an Irish trip - K Club or Druids Glen

I'm uneducated on options south of the border...so open to ideas from forum members down in Engerland....

Fire away !
