Hope this goes well for you. How much longer on the ship? Are you having symptoms or only a little off as you mentioned? It doesn't sound like they are taking very good care of the passengers.
You say the concierge sent you drink and snacks, what about a non suite passenger they would get nothing. I think I am hoarding a few snacks and drinks in my cabin just in case. I hope they get their act together as covid isn't going away for awhile.
