1) How many nights would you recommend spending on Lake Hallstatt? What towns are the best for lodging and a base? Hallstatt? Obertraun? Bad Ischl?
2) Is it easy to get from one town to the other in the evening? looks like there is ferry service in the day?
Any insight will be much appreciated. I should add we will be head to Salzburg aftewards then on to Munich for the end of Octoberfest and my friend's wedding.
