I think you need to give us a bit more information, will you be working down here and if so where. Also do you have your own transport or public transport.
I normally holiday in West Cork myself, more than enough down there to keep you busy. Not a lot of shopping though unless you go somewhere like Bantry or Clonakilty. Another option would be East Cork, Midleton or Cobh and herself could get the train into the city. I had an excellent weeks kayaking in Bantry bay last year, I was lucky enough to get good weather.
