Carnival Corporation’s fathom brand will be reducing its Dominican Republic commitment, while adding alternating cruises to Cuba.

The 710-passenger Adonia will start sailing to Amber Cove in April 2016, offering passengers a social impact experience, and begin alternating seven-day cruises to Cuba in May (2016), according to Arnold Donald, president and CEO of Carnival Corporation.

Donald said on a press call today that he expected to prove out the concept of fathom over the next year so and possibly add more ships.

The starting price to the Dominican Republic is $1,540 including port fees and taxes, while the Cuba cruises start at $2,990 excluding port fees and taxes.

Tara Russell, president of fathom and global impact leader for Carnival, said the Cuban pricing was aligned with other Cuba products and well positioned in the market. And since negotiations are still ongoing with Cuban authorities, port fees and taxes have not yet been finalized.

The plan is to call at three Cuban ports yet to be determined during the seven-day cruise, according to Russell, who said that there are 11 viable ports in Cuba.

Passengers must spend eight hours ashore in immersive activities during each call, according to current regulations.
