I'm arriving in Frankfurt on Friday morning, September 25th. I have to be back for work on Sunday night, September 27th. Originally, I was going to visit some friends that live near Wurzburg, which I have visited on many occasions. But due to unforseen circumstances they cannot meet me. I have no idea what to do. Should I stay in Frankfurt and take a train somewhere? I have spent a day in Frankfurt many years ago but remember it as a large city. I have traveled a lot but I'm a bit older now and am traveling as a single gal. I've read many of the blogs about Heidelberg. Some like it, some don't. Is there another destination that someone might recommend?
Thank you in advance for your suggestions
