@georgeob1,
You'll have a splendid time at the Adlon and your granddaughters will enjoy the Berlin Wall, rather the artwork that has taken place there. My daughter was very impressed with Berlin.
We spent some time in Munich last month and upper San Diego is still paradise like, although we have an abundance of tourists here right now which makes maneuvering through our tiny town quite difficult.
I was thinking about you - a German friend of mine has hosted the SF boat show a week (or two) ago and she is managing the next SF yacht/boat show in January 2015 too. She made pictures very close to your yacht club which made me think that she probably was there as well. In June she hosted the yacht/boat show here in San Diego and sailed with Dennis O'Connor.
