As our cruise gets closer, I'm wondering what specific plans people from the US are making in case they (1) test positive in a foreign country before embarkation and can't board or (2) test positive before returning to the US and can't fly home. We will be in London for a week before our cruise and then sailing from Ravenna . Currently, my plan is to test using the proctored eMed test before we leave London the day before the cruise. That way, if we are positive, we are at least in a country where we speak the language to make arrangements to quarantine before returning home. Then, we plan to test on the ship the morning that we disembark (we are scheduled to fly out the next day), again using the eMed tests, so that if we are positive, we can at least ask for help from RCCL to make quarantine arrangments. This seems like a reasonable plan to me but should I be doing more to prepare for the possibility of having to quarantine in another country?
