I chose this cruise and ship because I was impressed by the indoor pool / cinema feature and I liked the itinerary which took me to 5 countries I might not have otherwise visited....Hungary, Croatia, Serbia , Bulgaria and Romania. It was very informative and the ship, staff, food and facilities onboard were excellent. The gym and pool I used a lot and the talk/ slide show by the cruise director was very good. All local guides were very well informed and I enjoyed all the meals onboard. Having bikes available to use was a bonus. We had lovely weather which helped. A GPS tracking system showing where the ship was at any tome would be a very good addition, however we were given complimentary guide books and river maps which was a nice touch. I would definitely recommend this cruise to friends who wanted to visit eastern Europe on a travelling hotel!
