Dear KT,

If you include Brussels on your itinerary be sure to drop in on us for some hospitality and music! (You can get a cheap Eurostar (300 km/hour train de grande vitesse) ticket from London to Brussels and Bruges (a "must-visit") is a quick and cheap train ride from Brussels) The cafe and music scene is actually pretty active all year these days. I fully endorse the other suggestions made above plus would add Copenhagen as a great place to visit at that time of year.

Peace
