This is a thing? I've only stayed at Premier Inns (a budget UK hotel chain) and have never heard of anything like this happening.

High end hotels are more likely to follow the fads in my experience. The cheap ones have a door but it might be damaged

I've seen it in the US in smaller dense urban rooms and it's honestly something I've never thought about.

It's honestly something it would never occur to me to write a blog post about. But I guess it's one of those things that some people are sensitive about.

I first encountered it at a Hotel du Vin (UK) about 10 years ago.
