I chose this cruise because I like to go to destinations that not everyone goes to. This cruise was great. The ship was amazing and the staff were excellent. The food was terrific. The hotels that Viking put us in were top notch. I would highly recommend this cruise as well as the post extension to Brasov/Transylvania (if you are ending the trip in Romania). I did all the included excursions. I also did the optional excursion for the Behind the Scenes at the Opera in Belgrade. I suggest that you take this excursion, it was amazing. The tour guides were great and they speak English very well so that wasn't a problem. Just remember to bring small bills to tip the drivers. And I always tip the bus drivers as well. I can't comment on the entertainment on the ship because after meals I always went to my room. at that time I took the trip, we had to covid test every day and wear masks. It wasn't as horrible as most people make it out to be. first time I didn't get sick during or after a trip. The only think negative I have to say about Viking is that you have to pay for trips so far in advance and the only thing that stinks is that it's a pain to try and get that date changed to a later date.
