Ferry from Harwich to the Hook of Holland, ICE train to Munich via Dusseldorf. On the way back, the same route, except I took the night sleeper from Munich to Amsterdam.

Sleeper berth was great - free red bottle of wine to go to bed, your own shower and toilet, and only 160 Euros, so as cheap as a hotel.
On the way back booked a day cabin on the ferry for the afternoon snooze.
The SG meeting went well. Enjoyed the Christmas Market in Munich in the evening, and the liver dumpling soup with beer in the evening!
