We are going to use it in March when we return to Canada from our cruise.
How long do the tests take to do for a family of 4? We are thinking we can do it from the the cabin at 6AM right when we dock in port and can get a cell signal.
Otherwise, we are thinking about getting internet on the last sea day to just do the test.
I just got off a Carnival ship, and used the SwitchHealth antigen test with no problem at all. The test is easy to do and results are fast. I've used the PCR as well for the flight home to Canada with success too. I highly recommend these, especially for anyone in BC where we can only test in person at a few places and the cost for the antigen test is $126 (Kelowna airport)
