A question back for you: Why would you NOT go?
If you are thinking you're too young - don't. You might not get hired to work a D-I conference, but there will be people there who can get you into D-II or III conferences, and you will put yourself on some D-I assignors "radars"...how is that a bad thing?
Worried about going and screwing up? We all worry about that. The benefit for you is that you're young!
They expect that from the young ones and are more willing to work with/help you move along...
Worried about the $$$...can't help you there. That's an expensive camp - but they pretty much all are these days.
Go! Have fun! Learn! Get your name and face out there...
