If you do decide to go, I would reiterate to be very careful the excursions you are planning to take on your cruise right now.
We are on a 12 day cruise in Aug, and so many on our roll call have booked bus tours in each port. In my opinion, this could be risky right now, even with a mask on, because of contact tracing- one person on that bus becomes ill, or tests positive, it could effect everyone on that tour ( even if it is just having wait on test results) I understand that in normal circumstances these are great tours to take if mobility is an issue or you just want to see the sights. But I would be cautious right now. I hope things look a little different in Aug than they do now.
