I've just booked cruises for July and November - I don't feel comfortable booking anything any sooner just yet. I think I'm about convinced that there is no more realistic possibilty of avoiding covid while still working, so maybe I'll get comfortable faster than expected.
It's especially tough because we have some really, really attractive rates offers, plus several cancelled cruise credits associated with some extra onboard credit. I'm not sure Carnival will extend the window on using these, so I might have to bite the bullet soon regardless of my discomfort.
