Length and Composition was reason we booked this specific cruise. We discovered that fellow passengers make the difference between "excellent" and truly "outstanding." Of course, Viking does not have much control over this variable. So, as practical matter, our first portion, i.e., Amsterdam to Budapest, proved to be overall best experience. This first portion was therefore more satisfying considering the folks that we met and enjoyed during this portion of the cruise--several have become lifelong friends. That said, the remainder, i.e., Budapest to Bucharest, proved to be also very rewarding based on cultural and geographic sights as advertised, expert tours, and continuing excellent ship amenities. Not having to change cabins while transitioning from first portion to second was also much appreciated! We will travel again with Viking albeit not these same two itineraries. In fact, we recently booked Viking Alaskan cruise plus post-excursion for May 2019; looking forward to it with much anticipation!
