As part of my Europe Trip, I am planning to visit Paris, Switzerland and later from Switzerland (Lucerne) I want to go to the following four places but unable to figure out best common place to make as “base” location for economical accommodation (hotels similar to IBIS Budget hotels) so as to cover all these four places within best reach of train stations (got Euro pass).
1. Rhein falls
2. Black Forest (Schwarzwald, Triberg waterfalls, Titisee Lake)
3. Neuschwanstein castle (Fuessen)
4. Schönau am Königsee
Please advise best common and nearest base location for above four locations and also will 3 nights – 4days of stay will suffice as I need to proceed to Austria from there.
