Note: this has technically been the law for a few years but it was not enforced, esp during COVID, nor did many smaller hotels have the software needed to even enter foreign names.

Other short stay hotels wrongly assumed they needed special licenses to house foreigners like long term accommodation.
on an unrelated note, almost nowhere in the uk has "the software needed" to enter foreign names. Not just small hotels - not the government, not banks, not unions, it's a fucking nightmare. "oh, the details on your id don't match th..." 🫠 I'm 🙃 so 🫨 fucking 😵💫 tired 💀
