I hate this wishy washy ness but do understand safety first. Nov 1 seems so far off. I also hope vaccine passports will help with getting the cruise industry and international travel moving forward.
As of now, I'm holding off on booking a cruise until Dec 2022. We were supposed to go for New Years 2020, but of course didn't. Not ready to wait and hope so we booked a land trip to a Caribbean island for Dec 2021 instead. But def want to do a cruise Dec 2022!
