We boarded Odyssey yesterday, and I am posting this from the ship, at least if you see it I will have.
We had booked a window cabin on Deck 4, and discovered at check-in they had moved us to a balcony cabin on Deck 5. That was a relief, even though I finally had to go on a scavenger hunt myself to find our luggage on Deck 4.
Deck 4 is an isolation/quarantine area, complete with red warning signs, PPE, etc.
