GENEVA — MSC Cruises says it’s full steam ahead for two new ‘Meraviglia-Plus’ ships to feature increased tonnage and overall size.

The cruise line made the announcement at the coin ceremony for MSC Meraviglia held this week in Saint-Nazaire, France. The two new next-generation ships, known as Meraviglia-Plus, will have 2,444 staterooms and a double occupancy of 4,888 guests.

MSC Cruises also revealed that the two new ships will be completed respectively in October 2019 and December 2020, completing delivery of the last of the now four Meraviglia STX France made-ships nearly two years earlier than expected. The two new ships will be worth $1.7 billion, thus bringing MSC Cruises’ investment for the two Meraviglia plus the two Meraviglia-Plus ships to a total of $3.2 billion.

MSC Meraviglia will be christened in Le Havre, France on June 1, 2017. From there she will set forth for her inaugural season in the Mediterranean, homeporting in Marseille.
