Bowen,
I don't think there's a coaching fee----at least not to my knowledge. It's $450 for 30 minutes. He is an AFF instructor at my dropzone, and he organizes these tunnel camps every few months. About 5 of us (including him) are meeting up and driving down together. I think I'm the only newbie in the group. He instructs us based on skill level, and mentioned I'd be working on heading control, forward and backward movement, turns, slow and fast fall rates, side-sliding, knee turns, some docking. I'm not sure how many session there are, but I'm guessing it will be 2-3 minute flights. I *think* there is a video de-briefing also.
Thanks,
Tom
