The US Center for Disease Control and Prevention lifted its no-sail order on November 1st.
However, Royal Caribbean will be looking for volunteers to embark on trial cruises.
These cruises are a way to test safety guidelines the CDC has put in place to allow ships to set sail again.
Most cruise ships have been at dock since March, when the coronavirus pandemic halted all travel.
Royal Caribbean is going to be looking for volunteers to experience the new style of cruising.
The process will use simulated voyages to "test cruise ships" ability to mitigate COVID-19 risk.
