We did the eMEd tests ordered straight from eMed.com. The 6 pack was $150, cheaper than ordering the exact same tests from RC.. They worked like a charm. Logged in and the online nurses were perfect on execution of the tests. All passed, and we printed out our PDF sheets saying we passed...
That being said- the check in process involved showing the nice folks at the terminal our sheets, and they checked them off when they saw the word PASSED and the date of the test. Ahh....would someone even show up to the terminal with a test that said FAILED. No, why? They wouldn't be allowed to board. Meaning that every single person there is coming in with a negative test written on a piece of paper, that someone reads. Do you know how easy it is to edit a PDF file? I can in about 1 minute. If I had just paid thousands of dollars for a cruise, and had a double bar on a test, and it showed I had Covid, and others in my party had passed ( so I had their PDF files handy), it would be extremely easy to create a new PDF for me using an Acrobat editor. Just saying... I have no idea if anyone did this, or would want to, but after our cruise (late May) all 4 of us came down with COVID 3-5 days after we got back. It wasn't bad, but we got in on the ship. So someone had it and brought it on board. Yup.
