Hello,
if you take the stairs, ask for the far most table for diner on deck 5, eat at the buffet at outside rush hours, enter the theater after the beginning of the show and seat on upper deck further in the front where there is not a lot of people, don't attend to the social activities, find a lounge chair somewhere else than the pool deck…. You will be able to apply social distanciation.
That's what we did, and we masked at all time except outside, and eating and drinking, and….. we still got COVID on Eclipse. 🤧
Have a great day
