I do find it odd that the Dream has test cruise dates set and not the Wonder. As the Wonder is only canceled through July 12th and the Dream is canceled through Aug 2nd. Plus the Dream is out of Florida and there is the whole vaccination requirement law thing. So if I am reading the tea leaves I would say the Wonder cancellation will be extended soon, and if I had to guess it would not be coming to the Pacific this year.
I think it just so hard to say what the rules should be for cruising two months from now when things can change overnight, Just look at mask requirements changed overnight at Disney World.
I personally could care less about vaccination requiremtns. I am vaccinated so I have protected myself as best as I can, so I would get on a full boat tomorrow with no questions asked. I understand not everyone will feel the same way as me, but that is how I feel.
