Sailed for our 32nd Cruise , first with Viking Ocean having sailed on their Danube river cruise on their Longboats. Consistent non overbearing service...very different than other cruise lines. No children was a big plus. Beautiful furnishings and fittings. Outstanding open seating dinners in all restaurants. Veranda cabin was excellent: bed was firm, shower and toiletries were above average. Low key evening shows were great. Planetarium was a nice addition along with the on board astronomer who had a powerful telescope on the top deck for planet viewings. Embarking and disembarking was Very easy. Included tours were good. We went on 5 optional tours which were uncrowded and well done. Free spa pool was outstanding along with sauna and snow room...unique, not crowded and high end experience...used 2x.
We traveled with 3 other couples we are in our mid 60s. Mostly over 40.. One fellow passenger told us he was 93 and was on a moderately active tour..did great.
Cruise was in mid July 2018, 7 day Barcelona to Rome with a 2 day pre cruise in Madrid.
Best summary: will are planning another cruise with Viking...
