On my recent Regent Voyager cruise, I met two young dancers. Regent subcontracts with an agency for talent. They had trained in Florida before joining the ship as group, ready to entertain. While this was their first 'stint' they would be onboard for 8 months. They had duties that also included helping out at other social events (Trivia, lifeboat drills, etc.) and occasionally escorting a land tour. It seemed to me they were having a wonderful time, albeit the hard work. I think it would be a great way to keep dancing and learning in these times.
