I would like to ask ( read the Covid Discussion information ) about the "pre cruise" testing. Just asking if anyone has done one of these 2 Days as we are flying out on the 19th and cruise is on the 20th and hope to board about 12:00. So if we are tested and proctored and it's negative on the 18th, does this satisfy the "2 day" prior to testing?
