Frankfurt is ugly so we choose Mainz. Unfortunately we had to cover three nights in Germany and spending this time in Mainz and Mainz only was not a good idea.
Gutenberg Museum ok, Cathedral, mighty as it is, ok, but then what do you do. Leave after one night, go to Heidelberg, Munich or else, dont belief what the websides tell you about how many attractiosn they have, they simply dont. Their Roman museum is the laughing stock of the century, all copies, nothing real, shameful realy, very disappointed!
Take a Rhine Rover boat, run by KD. But if you take a train to Bingen first, it is cheaper and you get 20% off when you show your train ticket.
come here just for the river cruise. In my opinion, the government and authorities can do more to develop it.
