MSC Meraviglia will make a one-off mini cruise from Southampton on 26 May next year.
The three-night cruise from Southampton will visit Zeebrugge in Belgium and Cherbourg in France.
Prices start from £440 per person, and bookings open at 10am tomorrow (Tuesday 20 October).
Zeebrugge is Belgium’s most important fishing port and features long stretches of wide, sandy beaches and the Seafront Maritime Theme Park.
In Cherbourg guests can visit the weekly food markets, the maritime museum La Cité de la Mer, pretty Emmanuel Liais public park, or visit Manufacture le Parapluie, a quirky museum paying homage to the umbrella.
