re: Belize status

Show up with a negative test w/in 3 days, or there’s testing when you arrive. I think test is like $50 or $75. They let you leave after the test and tell you they’ll contact your hotel if the test comes back positive. They will call where you are going to reach you, if positive. The line moves relatively fast (about 25-30 min to get tested) if you choose to get tested there. You pay, walk into an empty room in the terminal and they’ll swab you, one form to fill out with your info and where you’re going.

Return to US the testing is at the terminal, but you will need to wait for rapid test results. You need the negative results to get past security. Consider this when booking flight or water taxi services. Think it’ll take about 45 minutes to return.

On ambergris caye, the hotels are fully staffed, at least Alaia and Mahogany Bay are.
ETA: curfew is 9pm, but depending on what you’re planning it’s not too bad as most places would be closed anyways. Hotel bars are open until much later.
