Boarded Grandeur yesterday with 3 teens and 11 AM boarding time. Agent did NOT want to see any vaccine cards. Negative test, Set sail pass, passport (birth certificate for other grandchild). I asked again about vaccine cards - she said she didn’t need to see them. I was surprised, but they had all been uploaded in the App.
by the way, fastest embarkation ever. We did not stop moving. Agent said the 10:30 folks walked right on ship, and everyone following did same.
Edit:
@Jimbo , your reasons are exactly why we chose a 4-day cruise. 4 day cruise is 3 days less exposure, Their school starts in less than a month. Even if they get it, they’ll have time to recover before school.
