Each of the two excursions, both on the MSC Divina, will feature its own unique set of artists slated to perform, so seafaring fans will have to make some tough choices when deciding when cruise to take.

The first excursion is scheduled for Jan. 3-6, with Knife Party, Pretty Lights, Flume, Boys Noize, A-Trak, RL Grime and more on the bill. That initial cruise will stop at a private island in the Bahamas' Half Moon Cay. That jaunt will also boast "A Day at Sea," featuring pool parties and performances all day long as the ship returns to the starting port of Miami (a first for Holy Ship!).

The second cruise will happen Feb. 18-21, and feature Skrillex, Fatboy Slim, Bauuer, DJ Snake, a DJ set from Basement Jaxx as well as hip-hop artists DJ Mustard and Ty Dolla Sign.
