Wanted to take a Christmas Market Cruise through central Europe, stopping at various cities and markets along the way. We weren't aware until a couple weeks before sailing that many major rivers in Europe were experiencing RECORD drought and thus very low water levels in rivers. This almost meant our itin. would be severely changed or curtailed for obvious reasons. The previous 3 months of cruising on the Rhine did experience altered cruising. However, just 4 days before sailing and after some much needed rainfall, it was announced that we Would be able to sail the originally booked itinerary! Crew couldn't have been nicer! Food was very good, portions slightly small, but the cruise was a huge success. Great cabin as well. Unfortunately about 1/3 of the originally booked psgrs had cancelled after the possible changes to itin. were announced. So, the other 2/3 had a wonderful time, certainly not overcrowded. Ports were all excellent between Basel, Switz. and Amsterdam. Weather cooperated and no problems navigating the Rhine. We were so lucky! Loved the Christmas Markets, we had done similar before in central Europe, but never from a ship. The markets are so fun - if you tolerate the cold. It's not an experience that most tourists can identify with and the markets there are all similar and still unique. Small gym, and unfortunately most psgrs went to bed right after dinner. Evening entertainment was very good, most psgrs didn't get to enjoy it. Of course, no casino on most river cruises. Love the AMAPrima and the Christmas Markets!
