I am unable to avoid visiting on Sunday (when shops are closed), I usually use it as a travel day but for Rotheburg/Bamberg, I'm unable to avoid it.
So between the two towns, which should I do on a Sunday (ie which has the least interesting shops and more things to see that are open on Sundays).... I'm not a fanatic shopper but I do like to go and have a look at shops for souvenirs and also to support the local small businesses. Is there enough to sight see (eg churches, wander the streets, museums etc) to fill up the day ?
If not, I might stay an extra day in the area so I can avoid visiting on Sunday, but then what can I do to fill that Sunday - I'll be staying in Wurzburg at the time.
