It looks like we were both right. She was on her way to alcohol rehab. Although why her family let her take the trip by herself is a mystery to me. The family obviously knew she was out of control, but an escort would have been prudent (well, hindsight says so)
It sounds like her family are a lot like the Kennedys. They care about the poor and downtrodden of the world- but only in a general sense. When it comes to real, live people you can actually reach out and touch, they’re unable to translate their so-called good intentions into honest to goodness human interaction.
