We were on the Sunbird last year, and my parents have been a number of times on both Sunbird and Sundream. Sunbird is older, but fantastic. Really enjoyed it. Better entertainment than any boat I've been on. Food and service were fantastic! Seemed to be less selling of "extras" than on the other, larger boats. Constant activity (again, more than the other, larger boats). Napkin folding, bingo, line dancing, ballroom dancing, etc. All kinds of things to do. Would go again in a heartbeat and would completely recommend it. Mom and Dad actually did the Mediterranean on the Sunbird and really enjoyed it. They have also been on the Sundream, but found it a little less satisfying than the Sunbird. Fewer amenities, fewer activities and an older ship. I think they would definitely recommend the Sunbird over the Sundream.
i'm not trying to be rude or anything but the Sundream is older then the Sunbird. Sunbird is the old Song of America and the Sundream is either the Nordic Prince or the Song of Norway. the Sundream was Built in 1971 and the Sunbird was Built in 1982
