So my parents are both COVID positive, and as a precaution they cancelled and got credit. However, because we were in close contact, we got tested and figured out that not only would our county testing be the most convenient (easy walkup without any lines) but it was free even without insurance. We got appointments, but there really was no need. They also had several nurses there even with only about three people being tested. The results they give with the antigen tests are done by their personnel so there's someone to vouch for it. On top of that, the first thing we got were more home test kits, which ostensibly are for testing again after 24 hours. But I asked if these tests would be acceptable for something like a cruise, and they said absolutely and they get people doing that.
