I wouldn't waste my money on a camp.

When I was your age, me and 1-3 buddies just booked a Cycling / Tri- friendly Hotel at some nice riding/swimming locale (Lanzarote, Canary Islands), maybe with the options of a couple of lessons from a local swim coach.

We brought along our own training plan that we had set up (granted, we had some support/experience from our Tri- Club doing that).

This way we were flexible, could adjust schedule and be on our own time (drop a rainy ride or stop for food on our own schedule), without being told what to do.

Great memories of some cool late night partying during those trips too....try that during an organized camp!

Personally, I've learned a lot at the camps I've gone to. I'm not an elite athlete but I've gone from BOP to MOP over the last few years. There are a lot of little easy wins I would have picked up on my own.
unfortunately, our squad's camp won't be until next spring so not much help to you now.
