The Magic Librarities

I get to make my first trip to Europe, unfortunately for business reasons. Royal Caribbean Cruise Lines uses one of our systems on their cruise liners and they are launching their latest ship, Liberty of the Seas, from Turku, Finland. I am traveling to Turku to get the system on line and train staff. We will be sailing from Turku to London at some point and then I will fly back to US from London. Don't know how much time I will have to myself in either city, but any advice on good shops to visit would be appreciated. Time will probably be limited, so I might as well spend it shopping as there would be no way to do any serious sight seeing on this short trip.

I will be in Turku on April 16 and will depart London on April 23.

long time since i was in Turku but take a loot at wikitravel there might be something useful:
