Re. all these sea cruise cabins suddenly available.

Maybe that has something to do with the recent sharp spikes in Norovirus.
Basically, these cruise ships are ‘floating toilets’. (My daughter’s term.)
Ironically, these cruises have long been on people’s bucket lists. Do people understand the physical reality behind them?
Messing yourself, running to toilets and being sick most of the time has never been my idea of fun.
