While I missed the group that went in May, I am planning on 4 weeks in July-August, and am open to any and all suggestions. We arrive in Düsseldorf on the 12th, and spend the first night in Nürnberg and the second night in München. We will be driving, by the way, and staying in Ibis Hotels, which we reserved on the internet. Then on Saturday we are off to Grundlsee to a timeshare for one week. The following week we will spend 7 days in Oberstaufen in a timeshare. I have seen Lindau, Meersburg, Uberlingen, etc. and would like any other suggestions. I was thinking about Kempten, as I have never been there. From there we will spend a night in Haguenau, and hope to see Freiburg and Colmar on the way. The next night we will spend in Luxembourg City and hope to see Metz on the way. Any other ideas I might have missed? Thanks.
