This was our second cruise on the Explorer. Our previous one was when the ship was "young" - fall, 2016. We were so impressed that we chose another cruise 8 months later. In addition, the itinerary fit our vacation plans. After spending several days in Norway, we boarded the ship in Stockholm. Embarkation was very smooth. We arrived at about 2 PM and within a half hour were relaxing in our cabin, with luggage delivered. If only the airlines were so prompt! The ship was in perfect condition, with everything polished and clean. Service was outstanding, from the cabin staff to the restaurants to the spa and gym. The ship traveled smoothly, even on the one night when the Baltic was rather rough. The lecturer was interesting and informative, especially with regard to Russian history. Entertainment was still spotty (see our previous review). This is not a 1980 Las Vegas crowd. Food was good to excellent. We had meals in all three specialty restaurants. Compass Rose was fine, as were Prime 7 and the French restaurant. Pacific Rim was somewhat disappointing. This was American Chinese food - OK for someone from a tiny town I suppose, but for us it was boring. And the wait staff, who were non-Asian, were clueless about the food. We chose Regent shore excursions and they were excellent. While the excursions often depend on the tour leader, we must have lucked out as the leaders were uniformly good.
All in all, a five-star experience, as advertised.
Spacious enough for the two of us, quiet, well laid out.
