We are planning to visit Munich Germany next year, June. We would like to spend few days there and then travel north to meet my sister in Weiden. After few days with her, I would like to travel to Czech Republic in a rental car, visit places and my parents, pretty close to the border, Karlovy Vary.
My question is how expensive is car rental there (Weiden) and does anyone has any suggestions for places of interest or things to do?
The whole trip is very flexible and open for recommendations.
