Carnival Corporation, the cruise firm that owns P&O and Cunard, is facing a boycott from LGBT travellers after halting gay weddings on some ships.
The company was forced to stop allowing same-sex unions on its ships that are registered in Bermuda.
The British Overseas Territory legalised gay weddings in May last year, but the law was repealed last month following a change of government.
That legally prevented Carnival from allowing same-sex ceremonies on board.
A P&O Cruises spokesman said: "Carnival Corporation believes that same sex marriage should be legalised in Bermuda and therefore we are opposed to the new law. We are currently working with local interest groups in Bermuda and elsewhere to explore options in relation to this."
Some LGBT travel agencies have called for a boycott of Carnival cruises because the company has not moved the registration of its ships to another jurisdiction.
P&O Cruises has six ships registered in Bermuda, while Cunard has three. London-listed Carnival is the world's largest cruise operator with about half the market and a fleet of 102 ships.
