Annecy huh? Camped there last summer, me and the missus. Stayed at Le Solitaire Du Lac, great campsite and direct access to the lake for swimming, water is surprisingly warm but it was touching 40 degrees when we went.
The drive to Chamonix is super picturesque if you fancy a day trip to see Mont Blanc. You can even get a train to Geneva which I'm told is also picturesque but we didn't do that.
Alsace we did 4 years ago, also fantastic scenery and beautiful towns/villages, very germanic. We stayed near Colmar, in Eguisheim. Some stunning old places around there like Riquewehr. Close to Freiburg and Basle as well. Freiburg was lovely and they have Park and Ride.
I'm sure you'll have a great time, wherever you go.
We are off to New York end of April and then our camping trip is planned for San Remo in July.
