Our flagship staterooms are elegant and well-appointed, accommodating up to five guests. Day or night, you can also take the stage with the Tu sì que Vales, a large three-story theater that welcomes sports, games and international artists. ...and the Aperol Spritz Bar for cocktails before dancing all night in discos, a playroom to take you back to your childhood, and a real German pub. We look forward to welcoming you on board.
A service fee, calculated daily according to the duration of the cruise, the destination and the ship, is collected by Costa at the end of the cruise and paid in full to the staff providing the hotel services on board. Because of this, tipping is not necessary and you don't have to pay.
