What is the current situation with booking into a hotel at FRA while waiting for PCR test results? I will be travelling EDI-FRA-NUE with an overnight stop in FRA due to difficult connections. Plan A is to get a PCR test before leaving Edinburgh but in case I do not get my result in time then plan B would be to get a rapid test in FRA. However, I have heard that Hessen will not allow hotel check-in without a PCR certificate, although this has now been relaxed in Bavaria. Is this correct, even for airport hotels?
