We had a little bit of trouble finding PCR tests in Isla Mujeres but it was because it was over the New Year’s weekend and there were lines in front of several of the trailers offering the tests. The hotel stated that they had no openings on Sunday to get the test. Eventually talking to the manager we were able to get tests on Sunday afternoon for our flights on Monday. We got our results emailed at 8 PM and printed copies were in our check out information at the hotel.
By far, the biggest hassle for me was the two hour line at the JetBlue counter to show your test documents in order to get a boarding pass. It was the ONLY way to get a boarding pass. If you are flying airlines like JetBlue, Southwest, frontier, spirit, and you don’t have status with them to get in the expedited line you need to give yourself a lot of time at the Cancun airport. Especially on busy days. Terminal 4 had thousands of people waiting in hours long lines to get boarding passes on Monday.
