I am travelling alone. It will be my first time to visit Hamburg, which I've always wanted to see. I've been to Munich and Berlin before, which I loved. I'm looking forward to the Christmas markets, and doing some other tourism: maybe a Beatles tour and a trip to Lubeck and/or Bremen? Perhaps you can suggest a three-day itinerary. I like music at night-time, so somewhere where I can find a good gig and any decent jazz clubs.
