Seriously, try again with Monique's computer:

You'll get a menu to select anyone your teen has ever met, and they WILL show up regardless of how well your teen knows them. I would still leave the VC on the lot, just so that you don't have to worry so much about curfew. I don't know how late it is, maybe 11pm instead of 9pm? And if you fill up your lot with teens, and maybe use the mind-control mirror or something to make sure they're happy, so they don't leave, then you won't even have many adults show up. I usually have a couple adults show up, and about 10 teens. I just pretend the adults are chaperones
And use Inge's formal pigalle doors for changing:

It will work better, I promise!
