Good to hear you are both home
I have been looking over many cruise websites to see if current isolation policies are explained. Both celebrity and rcl now state that if positive you will be moved to isolation closer to medical facilities. I think but am not sure this is a recent change. As most medical facilities are on lower decks it seems clear current policy will be in non balcony rooms so no prospect of fresh air during isolation .
I certainly will not be cruising so long as they have this policy in place.
happy to take the risk of getting Covid and having to isolate but not if that means being on deck 3
