I am traveling to Europe in September for 3 weeks to meet up with my son and his family. The first week I will be traveling alone and then will meet them in the Ramstein area. I will take a train to Ramstein, they will take a military flight. We thought of renting a car on base (Sixt has a site there) and then driving the rest of the time. Here is a tentative itinerary, planned for 3 adults and a 5 year old boy.
Day 1 -Drive from Frankfurt to Rothenburg ODT (only because my husband was stationed in Hahn, and says RODT is beautiful and old, granted he was there almost 40 years ago).
Day 2 - Explore RODT
Day 3 - leave early and drive to Berchtesgaden where we will stay for the next 4 nights. While there we will day trip to Salzburg, Konigsee, the salt mines, Ramsau and maybe Kiehlsteinhaus if my son is interested (I have seen it).
Day 7 - Drive the Bavarian mountain road to Garmisch or Oberammergau or somewhere similar, set up base for 5 nights. While there, visit Linderhof, Ettal, Oberammergau (can do all of these in one day), Neuschwanstein, Zugspitz, drive to end of road in Lindau, maybe cross into Switzerland and Liechtenstein. We don't have to do all the castles, etc. I have seen them all, but will do what the family wants. My daughter-in-law is from Northern Japan and has been in Charleston, SC and southern Turkey the last 5 years. She wants to see some snow and mountains.
Day 12 leave the area, drive to Frankfurt and take our respective planes home. Has anyone driven the mountain road, it sounds like fun and that we would be able to see a lot of things while driving it. We also have to consider what the 5 year old would like, hence the salt mines and the Konigsee boat trip.
Would Trier be a better choice than RODT? What about Vianden castle in Luxembourg? Neither my son nor his wife have been to the European continent so they want to see as much as possible while having a homebase (not having to pack and unpack every night). That is why I thought of basing ourselves on the Alpine Road at either end. We will use AirBNB for our housing as I have had excellent experiences both in the States and Europe with them.
