Hey folks, as I know this is new - and YMMV. We just boarded Oasis out of Bayonne this AM. When we were checking in, we made sure we brought our vax cards and were ready to present. Here was our experience with the process.
Royal associate: "Hi, good morning. Are you both vaccinated?"
Me: "Yep"
My Wife: "Do you need to see our cards?"
Royal associate: "Nope"
So - the vax check just like the testing, are effectively perfunctory at this point. For show, I suppose.
Will be interested if others have the same experience.
