I have been several times in Baden-Baden and I find this place attractive (because it has Termes and also nice places for walking). This time I am travelling to Frankfurt and consider to spend some days there or in a similar place. My companions offer to visit Wiesbaden instead (they have been already in B-B though never in Wiesbaden, and they are not sure were we all are bored in Wiesbaden). So now we are thinking what would be the best decision.
Can you please advice what is the main difference between Baden-Baden and Wiesbaden?
What would you advice?
