My first four cruises were on Sitmar back in the late 80's. What a fabulous cruise line! The crew was to die for, especially when you were a single, pretty girl in your 20's! They were all Italian and Portuguese and the kindest men I have ever met. Food was fantabulous, too, as previous posters have mentioned. The ships were smaller and didn't have all the bells and whistles like the ones these days, but I loved my Sitmar cruises. They were probably the best cruises I have ever taken.
