There are fewer than 100 guests and crew identified for testing, including all in-transit guests (guests who sailed the previous Mexico voyage and remained onboard for the current Hawaii voyage), those guests and crew who have experienced influenza-like illness symptoms on this voyage, and guests currently under care for respiratory illness, the release read.
I don't think the Cruise Line is listening to the State and Feds. They are talking 100% testing, and if there are ANY positive tests, a full quarantine.
Great line from Breaking Bad applies here:
“No half measures.”
300 tests is way short of all passengers and crew.
