We have just returned from the Emerald cruise from Amsterdam to Budapest. We spent 14 nights aboard the Emerald Sun. Cabin 220. The boat was clean, stylish, and had enough space to accommodate all our luggage etc. The balcony room was very clean, bright, and comfortable.
The sun deck on top was large and comfortable, as was the lounge and dining area. We never had trouble getting seats.
We sailed with mostly Canadians and Aussies, with several Americans as well, it was a great crowd. We made great friends.
