@Jenni18 (or are you @Kate19 on a different profile?) -
It's true, ABB started using different ID methods for a couple (hopefully not to many!!) countries, like Korea (if I remember correctly). So seems China is another one. Apparently has to do with their laws re. digital supplying of govn't papers.
My feeling is that this will eventually spread to all countries and guests 😕
Another reason to make sure one gets the whole name from the guest after booking and does an ID check (and possibly registration) on arrival as do official hotels and other accommodations.
It's really unfortunate, yet it looks like more and more responsibility is being left up to the host and forcing us to tighten up our own 'border' controls.
