The first Royal Caribbean cruise ship to return to service just wrapped up its first sailing in Singapore, marking a major achievement for the cruise line that has worked for months to get to this point.

Royal Caribbean announced on Thursday that Quantum of the Seas completed its first revenue sailing after careful planning with Singapore’s health and tourism authorities.

This is the first cruise ship to be able to resume operations, and it is limited to residents of Singapore. Quantum sails 3- and 4-night cruises with no port stops, which Royal Caribbean calls “ocean getaways”.
