Apologies that this needs to be asked again. But , I’m leaving Santorini on my way back home to San Francisco in August/ September—-with a 20 Hour layover in London . Outside of taking the covid test 3 days before arriving into London plus filling out the passenger locator form, am I missing anything? Is it also safe to say i won’t / should not be able to book a hotel for one night in the city ? Or, is it recommended that I stay at the airport for 20 hours? For what it’s worth , we’re fully vaccinated and willing to take all the required tests but feel like I’m missing something.
