I found a site with a detail of prison activity.
You will see that there is quiet a lot of program and some of them can be in my opinion generating a lot of role play. It is as well a possibility to have part time player assuming a few hours activity role play in the sim via a special activity.
I think we have one project open for visit program but you will see a lot more in there
