I've been to Parent L once, a number of years ago. The fishing was ok for eater waldos, bass, hammerhandles. Several nice campsites. It tends to fill early, so you may have to take whatever is available for campsites. Since we don't know what you've told them about expectations, it's hard to know, but my suggestion would be to pick a different entry point with more options for fishing, camping.

Wood L comes to mind.
