I'm guessing but I take it you mean Sevilla or Seville in Spain not the Savoy or Savoie in France or Savona in Italy. Personally I wouldn't go there unless on a ship's excursion because it is a long way from Cadiz and there are initially some great things to see and do in Cadiz or even Jerez de la Frontiera. Don't get me wrong Sevilla is a beautiful city but if it were my first time in the area I would stay near the port to start off with. Good luck anyway. ....Neil.
Is that Jimmy Saville.......? Always DIY - cheaper and so much more satisfying than following the lollipop......lots of sites out there will help you. Try google and cruise ports call boards - the first result.
