What to Do on Visit From Drug Rehab?

My sister is 17 and has been in a court ordered drug rehab facility for the past 8 months.

She now gets 12 hours visits away from the facility, and on those visits my mother likes to have her go tanning, to the mall, get nails done, etc. I think that time should be spent going to colleges, the library … something like that so that when she is out she can do something with her life. My mom says this is her “reward” time and has elaborate plans for fun stuff.

What do you think?
