I think it's interesting that all three top European cities are in Italy! Just reaffirms my belief that Italy is the most magical place on earth. It's cool to be Italian! :)
I don't know anything about "Grand Circle Cruise Lines" (which came ahead of RSSC for small ship cruise lines). I also don't know much about SeaDream, but I believe they are a much different type of experience than most cruise ships, plus much more expensive, if I'm remembering right...
