Never tried that either. I bring a few glasses home after each cruise and add them to my collection. Needless to say, I've got a good collection started.
Try a Ocean Wave drink on your next cruise. Its blue in color,and is imported from Austrailia.---->(spelling?). It was suggested here on the boards last year. Man, was they right !
Happy sailing;
