My wife and I had a wonderful time on the Celina of the Seas cruise. Every one of the staff working on the boat were extremely helpful and attentive. Ronald in particular was extremely helpful, always ensuring we were aware of our upcoming itinerary. The trips were well organised (I would recommend doing the cycling on Cat Ba) and the food was nice too with plenty of variety. Would suggest 3D, 2N rather than just the one night personally. Recommend.
