Awesome; food by our Romanian chef unbelievably good. Take advantage of pre- and post-cruise stays in Prague and Budapest. We did Prague with Viking and Budapest on our own, and enjoyed both immensely.
Everyone under 40 speaks English, a side benefit of the Russians leaving Czech Republic and Hungary around 1990. Viking tours were educational and interesting, and guides were superb. Transfers were handled very well. The suite we had was comfortable and well designed, although we did not get much benefit from the balcony our suite had.
