Honestly I always assumed that on large booking websites, "2 rooms left" would be at least "legally" accurate somehow (like there are 12 rooms left, but only 2 of that exact arbitrary configuration of precisely 198 square feet).
Because if not, wouldn't they be opening themselves to a class-action suit some smart lawyers would be taking advantage of? Isn't that why we have class-action suits in the first place? (Whereas an individual property site, I'm less likely to trust because who's going to bother suing.)
If it's a lie, how are Expedia, Priceline etc. not being sued?
