"There’s nothing illegal about that."

Oh pleez, your own self....I do know better (with all due respect to your moderator status here).
Then you know very little about Cuba. If you don't choose to believe me, read some of the other travel forums contributed to by foreigners who have been going there independently for decades.
As one example, this quote:
"the government doesn't look too favorably on unlicensed casas from my experience in staying in one and MINIT inspectors showing up."
or this:
"DO NOT stay in a casa that is not licensed to host foreigners. …….could easily cost you more in the long run…… I have twice stayed in unlicensed casas--….. The first time an inspector came in the middle of the night (called by the woman's ex-husband) and we had to find new lodgings. Worse, she got a $400 fine ……. Second time, we were turfed out in the middle of the night in the rain because an inspector had been told ….that the casa was hosting foreigners. …… it did cost us a night's sleep, since our possessions had temporarily disappeared and we had no idea what had become of them until the inspectors finished their business and we got it all sorted out. Neither experience was one I would care to repeat."

Even a foreigner married to a Cuban has to apply for a special visa to stay in the house of that spouse, rather than a casa licensed for foreigners

As far as camping:
"Unless you ask and receive permission, you will likely be told to move because it is, as you know, illegal to camp--indeed, to stay--anyplace that isn't licensed to host foreigners. "


Your blogger herself admits that her trips to Cuba have been guiding tours with a Cuban to do the arrangements. That does not assume much knowledge of the country, just wrangling newbie tourists. She also admits she does not speak or understand Cuban Spanish.
