If you’re wary of booking a full-fledged cruise for 2021, there’s a great way to dip your toes in the water before making any commitments. Royal Caribbean is looking for volunteers for trial sailings to help test their safety protocols and other procedures before launching real cruises again. They’re looking for volunteers to participate in simulated cruises for their Volunteers of the Seas program.

The program’s page reads, “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. 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.”

The simulated trial cruises are part of the CDC’s plan for phased resumptions of cruising operations after the agency lifted its “No-Sail” order earlier this month.

A simulated cruise isn’t the same thrill as actually cruising through the Caribbean, but it might be just enough to tide you over until the real thing becomes available.

To apply, you just have to fill out an online form with some personal information.
