Individuals will still have to follow the entry requirements and Covid protocols of the countries they visit.
Guests who are not fully vaccinated, or have children in their travelling party, will still need to go ashore with an MSC Cruises protected shore excursion.
The move comes as the line announces its health and safety protocols for the forthcoming winter season.
For the programme, MSC will require guests to provide a negative Covid test result, proof of vaccination received more than two weeks before the start of the cruise for all guests over the age of 12 and Covid-19 insurance documentation.
