We took the trip from Regensburg to Walhalla and back. The Crystal Princess is a beautiful boat. Pluses- on time, clean, comfortable, and friendly staff. It is also reasonably priced.
The minus is that the waiter never stopped by our table on the return trip. But it is probably just as well. The people at the next table had to wait 25 minutes to get their drinks on a 45 minute ride. On the trip there the waitress went to the tables in a timely manner. I got my coffee within 10 minutes & others we served just as quickly.
I recommend this boat trip if you want to visit Walhalla. read more
