Are there inexpensive cruises that dont go to third world countries? (Not including the Mediterranean).?

Third world countries is usually used to describe developing countries without ties to capitalism. That's not the Caribbean. According to most lists, Haiti is the only country in the Caribbean that qualifies as one of the least developed countries. The very widest definition however does include just about the entire world that isn't the US and Western Europe. Even using that definition though you can cruise the New England cruises, Hawaiian cruises and Alaskan in the US. Western Europe and Baltic in Europe. However I would hardly put Acapulco and Puerto Vallerta as underdeveloped. The Caribbean has Puerto Rico, US Virgin Islands, BWI, and the Bahamas. None of which would be poor. I'm not sure your definition of inexpensive cruises. All ports have port fees. When a country wants tourism, it has low port fees per passenger. Many other ports have high port fees making the cruise more expensive. How expensive a cruise should also include your cost to get there. For me, flying to Italy would be far more expensive. Of course cruises from there go to Turkey and Egypt.

if you stay at the port you usually dont see the sad depressing stuff but if you take excursions you will drive right thru it. we couldnt believe how the poverty was in st thomas. some people didnt even have walls and you could see them doing thier buisness __ not the vacation sight i wanted to see.
