We were supposed to board at Amsterdam to Budapest and instead we ended in Rotterdam because of some tall ships celebration at Amsterdam. We were not aware of the low river water level until we arrived and boarded a sister ship instead. We were told half way of the cruise we would meet up with our original ship where we would be transferred into.
The service and activities were excellent. The ports and shore excursions exceeded our expectation where some inconveniences such as unable to dock at certain port were bus there and compensated with extra activities.
The dining and entertainment aboard the ship were excellent.
