I won't have a car. I'll be using public transport. I appreciate your insight about the industrial area in Basel of where the Courtyard is. You are right; I don't want to be in an industrial area. I don't want that in Basel or Saint-Louis.
Colmar is on my list as is Freiburg where I lived in 1982. I haven't been back since and am eager to return. Thanks for the info about Luzern.
