I thought the response in the Bad Schandau tourist office was disappointing and the welcome luke warm. I felt that I was a nuisance in asking for advice and recommendations as to where to go and what to see. Did not venture back there during my stay despite having further questions.
Staff is very helpful and you are also able to arrange for rental bicycles there - it helps if you understand and speak a little german - but usually there will be assistants there who speak english also!
We were there looking for information to get to Bastei. The lady at the desk did not speak any English. So we missed the bus which runs to the bottom of Bastei trek and we had to walk 4kms to get there. The frequency of the bus service is around 1 per hour. So be prepared for it.
