It will take time to re-boot ships in terms of - fuel and power systems will need checking, and double checking, the Coastguard will have to inspect for safety compliance, whole liner disinfected, staff will have wandered off, suppliers of food will have gone bust, suppliers of knives and forks and cleaning equipment etc etc no longer around, some staff will of course be dead, entertainers will think sick on a disease ship or stay home? and will stay home. August! No my guess is next year.
