It has probably been a bit of a holiday for many crew members. Without passengers, crew are often allowed to use the swimming pool and gym. Without the need to service suites, housekeeping and butlers would have a lot more down time; waiters and bar staff also; kitchen workers. Laundry workers wouldn’t be quite as busy. Possibly some spring cleaning going on, maintenance, and crew drills. The logistics for crew changes will be another headache for Silversea, but the crew themselves have probably been enjoying the break.
