This is a restart for many lines that will be restricted to about half the passengers they normally carry. They should be able to meet that with a vaccine requirement.
In the long run I believe like you, that they will not fill the ships too full capacity if the vaccine requirement remains in effect. Only hardcore Cruises will go.
The way it shaping up, people will have to be vaccinated every year as the Covid vaccine appears to wear off yearly. -Tom
WE hve relatives just getting over Covid and they were told to get jabbed. Apparently, naturally created antibodies are up to par.
You couldn’t pay me to take a cruise before covid. No interest these days.
