See that beginning September 3rd, Those vaccinated will not be required to do a negative Covid test before embarkation.
Also see unvaccinated cruisers will now be allowed to go with a negative Covid test taken before boarding.

This was a big issue at Jason's town meeting on our last cruise. A Doctor who has been very involved with the Covid problem stood up to explained it was time to realize that we should be treating Covid like a common cold
for those people who are fully vaccinated, and stop this continuing required testing for them. The room erupted with people clapping.

Don't know if this had anything to do with NCLH decision, but something, but something happened.
