With Righties saying they're not getting vaccine passports, is it fair to say that this summer's vacations will be a lot nicer?

I like cruising, and it appears cruise lines will require proof of vaccination.  A lot of people are saying they won't get vaccinated so they won't be cruising.  That's just fine by me. I NEVER talk politics on vacations, but I've run into trump supporters who use can't shut up.  I generally do my best to avoid them.  I don't really care who someone voted for when I'm on vacation.  Vacations are no place for political debates. 

No, because as long as people don't get vaccines, there will continue to be daily cases, and things will continue to be closed. The rest of us will suffer for their selfishness. 

We'll have a third wave, no vacation, if not enough people are vaccinated. 

Yes.  All vacationers would then be wearing masks.
