How flexible is the 72 hour Covid test-for-travel window
How strict is the 72 hour window for getting a negative PCR test to travel to the Canaries? From what I've read, you have to show your result/certificate when you “book in at your accommodation”. We will probably be arriving at our hotel at around 4.0pm on Sunday 20th December. So does that mean we need to have the PCR tests taken anytime after 4.0pm on Thursday 17th, or is it not that strict?
What if the clinic's last appointment is 3.0pm on the 17th, and we don't arrive at the hotel until 5.0pm on the 20th (74hours)? Apparently, you get results back by midnight the following day.
I think it will be too nerve racking to have the test Friday am, and wait to get the results by midnight on the Saturday, before the following morning's flight.
