The list is very unbalanced and shows a lack of knowledge or at least an unbalanced view of the world. There are some ten itemised destinations in a list of 18 around north America. Yet
Europe and
Asia which is about 60% of the planet get just two mentions.
I think this guy really needs to get out and explore the world a bit and realise we dont just orbit around one continent. The
Indian ocean and the
Mediterranean are just two of the world's great cruising regions.
