If you look for the city itself diring das time I would recommend Cadiz for its typical restaurants. If you stay overnight Marbella has some excellent, and expensive, restaurants.

Not a tour but an option: The historic Rhodos town is right next to the cruis port. There you need to walk anyway, thus you could see as many or as few of the sights, alleys, churches, palaces and museums as you like on your own. Once you have passed through the ancient part you get to a large square where you also find most busstops. There is a direct bus to Kallithea Springs, running every 30 minutes.

Yes, testing is free for all in Germany. This is supposed to stop by the end of June, but might be prolonged.

In my experience, yes, each person can link a different credit card to his or her account and cruise card.

Actually there are various places where ships dock, thus there is no simple detailed answer. Nevertheless, there should be a stop not to far away as the bus follows partly the river.

I am glad you found something you can look forward to. Enjoy!

Everything is electronically recorded, thus it would be difficult to serve you a beer nobody is charged for. Of course you can always get a drink above your packages limit and just pay for it. Which package suits your taste best you have to decide.

Genoa will probably the largest share of people disembarking but it is still rather simple with staggered times like on other shops. 10 am should be no problem at all.
