Cities of Light cruise starts in Prague for a few days. Stayed at the Hilton which is an easy walk to Old Town. Did the Lobkowicz Castle extra tour was lovely with lunch and a 3 piece musical concert. Info makes it look like the Prince will greet you, not the case. Only thing that could be improved is with tighter security into the Prague Castle grounds that Viking add time to itinerary so you can have more time on the grounds. We had no time to see other parts of Prague Castle had to get to lunch.
Bus ride to Nuremburg for free time and then board ship in Bamberg. There is not a lot of time in Nuremburg just enough for lunch. Did get to Zeppelin Field only, able to drive by Palace of Justice.
Bamberg on Sunday morning was nice but nothing open. Had to be on boat by noon to sail.
Clean, good housekeeping and very unobtrusive, nice toiletries and towels. Well laid out. Balcony was nice to sit out on in nice weather.
