We took excursions in every port. And they varied from fantastic to boring. Sorry to say the latter outnumbered the former. Sometimes I suspect HAL had found their guides on the street.
HAL provided us with many high quality lectures in the main stage before many of our ports. They were often so popular that the latecomers had to sit in the stairs.
Eurodam is very beautiful seen from outside. But it´s function is in many aspects inferior to the much older "SoS". Many of the open decks in front were closed to passengers. (Security reasons.) Eurodam lacks the open top-deck. Instead one open in the back, and a half-open in the middle. I did not like the layout and design of some public spaces. (Bars etc.)
First 8 nights we had a standard inside cabin. Avoid it! Fantastic large beds and good ventilation. But no floor space. Go for the large inside (with a sofa), unless you not travel with friends with larger cabin.
Last 9 nights we had a veranda-cabin. And it was perfect in every aspect. (On SoS we had the second largest suite, nr. 8000, but the much smaller in Eurodam, was in some ways better.
Food and service was superior than on the cheaper SoS. But I did not experience better food in the restaurants, Pinnacle and Tamarind, who charged extra. We had the best dinners in the main restaurant, Rembrandt. And the best service.
Entertainment had it ups and downs. Mostly inferior to SoS.Would I go with HAL again? Very probable. If they are 20% more expensive than for instance RCCL, they give you 20% higher quality. (meals, cabins and service.) Would I go with RCCL again. Yes, roughly as probable. Or I will never cruise again. (Not so probable.) Or perhaps I choose i River Cruise.
