I've been reading about the area around Frankfurt when I'm going for a week in June, and all three towns look interesting. Which of them would anyone particularly recommend?
Looking at bahn.de, it looks as if I could get a Hesse Ticket and do all three in a loop from Frankfurt in a day with a couple of hours in each, and then maybe go back to the one that looked most interesting for a whole day. How close are the stations to the interesting bits of the towns?
Or is there anywhere else that would be a nice trip out from Frankfurt (I'm already going to go to Darmstadt for at least two days)?
