I believe it will take months not weeks to implement the onerous multiple CDC requirements of a bureaucracy.
It looks like CARNIVAL can withstand a longer delay than other cruise lines, but to me NORWEGIAN remains the weak sister. ROYAL CARIBBEAN is questionable.
A lot will depend on Tuesday's election results.
The fossil fuel guzzling cruise ships sill be doomed if Biden wins. -Tom
I don't know the relationships of the cruise lines, but since they should be in competition it appears to me CARNIVAL ,the strongest of the 3 top Cruise lines, should back off, and let NORWEGIAN and ROYAL go first to satisfy the CDC and if Covid has the CDC shut them down, both lines will be closer to bankruptcy since they spent millions to restart.-Tom
