The last line of the story says what is true: 7 day rescission period, and he did not do it. And he's out $8000. One thing about uneducated (don't know) people who go to these tours: they don't READ THE PAPERWORK. In this case, if this guy had sat down and read the paperwork, they would've seen the 7 days to rescind, they could've sent it in, and walked away. So, I would say it is 50/50 fault. MAYBE the resort could've been more forthcoming about the rescission, but it is also their fault for not reading how to get out of it.
