All new bookings made by 31 December 2020 for any cruise from either brand departing before 31 October 2021 can now be amended once free of charge.
The option applies until 21 days before departure.
Chris Hackney, managing director of Marella Cruises and Tui River Cruises said: “We understand some customers may feel a little uncertain about booking a cruise whilst travel advice hasn’t changed.
“We wanted to offer flexibility for those wanting to secure their summer 2021 cruise with us, with the added reassurance that if they no longer wish to travel they can amend for free.”
