I am one of the "young couple" that Joanna is talking about. We did take a SeaDream cruise in January and loved it!

Service was the best I have ever experienced, food was outstanding and the number of passengers was perfect.

The only negative I can think of is that cabins are definitely smaller than Radisson and lack balconies. At first I was hesitant after being spoiled on the Diamond, however at the end of my cruise I did not miss it at all. SeaDream has so many open air areas, and dinner is served under the stars several nights during the week, also the ship is equipped with some fabulous Balinese sun beds that you will really enjoy.

I would have to rate the SeaDream as one of my best experiences ever, from the itinerary, to the crew that I highly recommend you give it a try. I don't think you will be sorry.
