I would like to see some nordic ports.
Like Helsinki (Finland) http://maps.google.fi/maps?f=q&hl=fi&geocode=&q=helsinki&ie=UTF8&ll=60.148341,24.942398&spn=0.083737,0.2314&t=h&z=12&om=1
or Hamina and Kotka (Finland) http://maps.google.fi/maps?f=q&hl=fi&geocode=&q=kotka&ie=UTF8&ll=60.457218,27.100525&spn=0.331796,0.925598&t=h&z=10&om=1

Lots of small islands and maybe cold weather. Real winter would be challenging
