I'm not defending the other issues but the sleeping accommodations wouldn't bother me much but this would all depend on how much I paid to get there.
Well, the last part is key.
I wouldn't mind sleeping some nights in a tent, but I sure as feck wouldn't pay two hundred dollars per night for it.
Anyway, this isn't really about the money - more about (possible) false advertising. If people actually get what they pay for (if these accommodations are reasonably close to what they were sold as), then it's fair enough (if stupidly expensive). The less close they are, though...well, there you go. Fyre Festival and so forth.
