Rather like Caribbean Cruises, there are not that many South American Cruises from Southampton. Due to the distance, cruises to South America do tend to form part of World Cruise segments; however one or two cruise lines are introducing them; a couple are listed below.
South America Cruises from Southampton will often visit a few islands in the Caribbean; this is done to break up the cruise; after all not many people will want to spend ten days or so on a cruise without touching down in a port.
The length of South American Cruises from Southampton tend to be between 30 & 40 days; however if the whole of South America is visited then this can extend up into the 80 and 90 day mark.
