How much time does it take to do test and get results? Are there any guarantees? If there aren't then we are very vulnerable consumers.

Logistics of isolation hotel schedule...

What happens if you arrive after midnight (as I do)? Even if after two long flights, I ignore jetlag and get up to have the PCR test at say 07:30, will it be ready for check-out time which presumably is noon? I suspect it couldn't be, so I am booking a second night, which fortunately (for most hotels) is 1/3rd the price.

What I find bizarre is that the PCR test is not done right at the airport. This is how they did it in the winter to spring in Dubai (free), France (free) and Turkey (do not recall). In any case, you didn't get it done hours later at a hotel or hospital. Has medical advice been consulted about whether this is common sense?

On the related subject of transportation: is the shuttle from hotel to hospital solo passenger? Otherwise we potentially expose driver to COVID.
