Fathom cruises will include conversational Spanish classes for passengers to learn a handful of useful phrases before their arrival in Cuba or the Dominican Republic.
The social impact cruise brand said the Spanish, for those who don't know it already, will help guests work alongside and engage with locals, which will heighten the satisfaction of the cruise.
Fathom said it will also offer dance lessons that feature some of the popular dances, such as merengue in the Dominican Republic and the salsa in Cuba.
A cinema series will showcase films made in and about the two countries.
Stores on the 704-passenger Adonia will offer a "one-of-a-kind" collection of merchandise from "purpose-driven businesses that empower local entrepreneurs around the globe," Fathom said.
The Adonia will keep its Ocean Grill restaurant and Glass House bar, but Ocean Grill will offer an experience "that extends beyond the flavor-rich foods to help travelers further immerse and understand the cultures they will encounter," Fathom said.
Fathom, a Carnival Corp. brand, begins cruises next April.
