We are looking for a tour of Warnemaude and it's surrounding cities. We are a family of six and would prefer a private tour. So very difficult to find anyone!!! Any advice?
There is a company that offers exactly what you are looking for, and they get rave reviews at Tripadvisor:

But maybe it's too late and they are already booked out. I also found this one:

but without a proper About Us- page and reviews I would be cautious and ask them a few question in advance before I book. But the tours they offer look good
Or you could opt for the tour the cruise company offers, which is probably very expensive, or do it on your own, which can be very cheap. If you use a so called "Länderticket" and travel by train it would cost you ~60 €uros. There is also a Hertz rental station at the pier, and a minivan for seven (Ford S-Max) costs ~150 €uros.
