We were denied boarding on Friday's Dream cruise. We had two parties, my husband and I and a friend. We had separate reservations, separate rooms. Our friend tested positive at the port, we tested negative. Since we all arrived in the same car, none of us were allowed to sail. They provided all of us with a voucher for a future cruise credit in the value of our original reservation, minus
travel insurance (we don't get that money back). We also had to call the port to get a refund on our parking charges.
We had to wait for our luggage to be retrieved (about an hour) and the paperwork for the cruise credit. We drove to the port so I can't answer on what happens if you come via bus.
The person who tested positive got retested Friday and received their results this morning and was negative. The port will not re-test, they will only re-look at the test you already took to make sure they didn't read it wrong.
