Have you had experience running (or growing up in) a (small) hotel or B&B?

for tl;dr reasons I've been wondering how much the experience of running a small hotel/B&B has changed in the last ~20 years. I distinctly remember as a kid staying in B&Bs that actually threw you out after breakfast - no use of rooms between 11 & 3pm or something like that. The idea of those sort of restrictions seems ridiculous in the google review era where you have to make sure everything is insta-worthy, and yet I’ve still stayed in some absolute dives that somehow make money. I’ve a lot of friends in hospitality but almost all in restaurants/bars, none in accommodation, and I’m really interested how the industry compares – is it struggling as hard? There was so much talk about airb&b killing the industry and yet… (that said, I know some guesthouse owners in Scotland who have given up the business because of the new tax). Have you run a guesthouse? Are you still running one now? How is it going/how was it?
