Hello again!
You will need to be COVID tested 72hrs before boarding your flight back to the U.S. Zivas resort will schedule a time for a free on-site COVID test 72 hours prior to your flight when you check in. They can print the results (for a fee) or email it to you for free. Should you choose to elect an insurance plan, you may do so at check-in. For $36, you can stay at the resort for free (and eat for free) if your test returns positive.
