I also noticed that some of the places are really, really nice in resort-style locations and some are very bare bones/basic. One of the recipients pitched a fit about being sent to a very basic place and was moved to a nicer place. She was on heroin.
What determines the plushness of the place they are sent to? I wonder if they have a set budget for the show, $X amount for treatment per episode with the factors being the length of time and the type of care needed? (Ie., the heroin ones seem to have replacement drugs & medical staff involved to get through withdrawal, maybe those are more expensive?)
