I thought I had a rough sense of what I wanted to do with this trip, but the more I research the more I find! We're cruising in the Mediterranean from Trieste and afterward have 11 nights to go up through Germany to Berlin to fly to Barcelona to sail home. The plane tix are bought, so the points are fixed. My teen ds wants to go to the Panzer Museum situated between Hamburg and Hanover, in the northern part, so I thought we'd work our way up, doing the Eagle's Nest, Salzburg, Munich, Dachau, Nuremburg, the Panzer, and finally Berlin. Then I found the Rhine River cruises you can do from Bingen to St Goar (maybe on the way?) and the Luther stuff over in Leipzig (other direction) and Wittenburg, the Wartburg Castle, the Bach Museum... And of course if you're doing all that surely you're stopping to see Mainz and Gutenburg...
So what don't I know here that would help me be more sensible? The Rick Steves Germany in 13 days (which I was looking at for ideas and reality check) makes a loop starting in Hamburg, but we're starting from the bottom, which ends up more of a Y. Do I give up on the things in the East? Do I toss the Med cruise to have more days? And is doing a lot of WW2 stuff great or wearisome? That's why I was looking for some fun things like castles, cooking classes, etc., to break the heaviness up.
The other thing is that this is in October. The cruise is the beginning of the month, which puts us into Munich just after Oktoberfest. We'd be going by Innsbruck, the Zugspitze, etc. My googlefu says it's pretty cold by then to be trying to do the Zugspitze, right? Is it an ok time to do that Rhine River cruising or is it really past the prime for that too? I've read in the fall water levels go down, but I thought maybe in that small section it would be fine. But is it overcast or less scenic in mid-October?
Any sensible advice on this? It seemed so simple until I started digging in and realizing HOW MUCH there would be to do!! And when we went to Europe last fall (Rome, Luxembourg, etc.) our favorite night was in Germany. The food was amazing, the hospitality great, the scenery beautiful. We were just there to see the dragon's teeth and keep going, but still it struck a chord. Oh, and does it matter on the common sense thing and how to whittle this down that I'm not planning to rent a car? I guess I could, as I did last time for Luxembourg. I'm just not a great lover of driving so it's just as easy to me to use the trains.
Thanks for any advice.
