I have read in one of my FB groups of people accepted and not having any trouble at the port.
Someone either on here or the other site posted this which I found very helpful. I cut and pasted and I am sorry I don't remember who posted it:
When you upload your vaccination card, it will show an option for claiming 90-day recovery in order to exempt from testing at the port. There will be instructions on what are needed in order to claim the exemption. You will need the COVID-positive test result issued by a lab or testing agency (like clinic or hospital) and a letter from a qualified doctor on an official doctor's office letterhead indicating that the doctor has examined you and declared you recovered from COVID infection and safe to travel again. Both documents must have your name, date of birth, and date of test and examination clearly listed. At-home self-diagnosis testing kit results are not accepted. Missing any of these and they will reject the document and the claim. DCL website doesn't mention this option and Safe Passage doesn't post their policy publicly online until you are logged into your account. Someone in this group have posted a screenshot of that recovery claim screen. You'll have to browse through the media section of this group to find it.
If you need straight from the source, call Safe Passage 877-250-5132 or email them at DCLsupport@inspirediagnostics.com with your full name as shown on reservation, reservation number, and contact number. Their call center runs 8 am to 8 pm EST 7 days a week but is closed until after New Year Day. Email is probably the best option so you have a hard copy to read and maybe post it for everybody in this group to see.
I am following this closely as my husband tested positive last week via a rapid test at home and hope to get a PCR test for both of us this week. If we test positive then I have to wait until we are both recovered, get to a dr and hopefully be cleared to travel. If not then we have to cancel. Cruise is January 22 and all docs have to be submitted 12 days before so cutting it very close.
