More than 100,000 people have signed up to take part in trial cruises organised by Royal Caribbean International.
The figure was announced by President and CEO Michael Bayley on Facebook, just four days after the company launched the initiative.
Over 22,000 signed up in the first day to take part in a mock cruise to test out the cruise line’s new protocols.
"Part of the process for any cruise line to receive approval to restart cruises from the U.S. Centers for Disease Control and Prevention (CDC) is to conduct a series of test sailings that have volunteer passengers onboard," the cruise company said.
Royal Caribbean has not announced any plans on when its test sailings might begin, although they could start as early as December.
It’s also not said how it would pick people from the public to help test out these cruises.
"We are still reviewing the CDC framework and do not have details on our simulated sailings," Royal Caribbean said.
"While we review the requirements proposed by the CDC and consider when we can host our simulated trial sailings, we are gathering information from those who have shown interest on our Facebook group and will be in touch with them when we have more details.
"Our priority is to ensure that we can exercise our comprehensive set of measures in a safe and healthy manner while making sure we provide a memorable vacation experience."
