The suggested format is that this is a discussion thread about the places along the route, links allowed in moderation, any food mentioned is vegan. Sort of like a treasure hunt for information, yet no teams, people sharing what they find.
A separate thread? If so, running concurrently with this one, or after this one.
Or moor Der Goldene Delfin here, get some land transport to the other river, then cruise on that river on her sister ship Der silberne Delfin then return to Frankfurt to continue the cruise along the Main?
What do you think would be best, bearing in mind all we need is our imaginations? The world is our... erm... I went say the word, due to this being strictly vegan.
I would say, moor up, and take a detour.
It'll be nice to include recommendations from people.
If everyone else is in agreement, I'd like to go to Frankfurt. I'd like to wander around the Old Town centre for an hour or so, have a coffee at an open air cafe and then go to see the Palm Garden.
So Der Goldene Delfin is remaining moored at Frankfurt and we can continue to explore Frankfurt, yet we can also arrange trips overland to Offenbach too.
