No, that is not true. While many of the cruise lines will redeploy many of their ships in the summer to other destinations that will be more profitable for them, the major cruise lines will keep some ships in the Caribbean year round.
In order to keep the sailing capacity of their ships at or near 100%, prices in the Caribbean market are very soft right now. The cruise lines would rather send their ships to Europe, Alaska and the Pacific where demand is high with prices to match. Thus, the cruise lines in the summer redeploy some ships to these other markets.

Blueliner is correct. The Caribbean is not that much in demand during the summer months as compared to Alaska or Europe so a lot of ships repo out of the area until the following winter.

That isn't true. As everyone else said, some ships are repositioned out of the Caribbean in the summer, but there are still ships that remain there.
