Chin is right that things can change between now and then, but as of now there is one US-approved Covid test and we are also bringing one of those for each of us. We are flying home on Delta and this test is sold directly from a link on Delta's website regarding accepted tests. It requires a video conference with a qualified health professional who watches you take the test and then confirms the results in an e-mail; and the potential problem is obviously an overload of the system on one of the busiest travel holidays of the year.
I also expect to use ours as a backup. We are not staying at Atlantis, but there is a restaurant called Latitudes in Nassau that apparently provides Covid tests for diners upon request. There are also clinics there, and we have the What's App contact for a nurse who will come to our villa and do the tests on site, but I read something about $170 per person charge, and if that's the case it will be a last resort.
On another note, does anyone have anything other than an email receipt for their tickets at this point? I purchased the UConn package with two mid-court seats to each game and that's all my email says, so I'm wondering how and when I will get the actual tickets.
