The facilities are incredible. We were there 2+ years and continue to be blown away by what we experienced...in terms of facilities. Never before or since have we seen anything like IMG for all its sports. They offer camps for adults too...if I had the time for tennis or golf I'd probably consider a week at IMG.
There were some excellent baseball coaches (Kevin Sharp, Edgar Caceres). Also some average coaches and some below average coaches.
For the cost/benefit, we concluded we could optimize school, sport, conditioning, etc., by doing it like most people do...a la carte. We've not been able to replicate the facilities anywhere, but we feel we've found everything else better elsewhere: academics, college counseling, baseball instruction, weight training/speed/conditioning, etc. IMG has all those things, plus it runs camps where all those things can be sampled.
Regarding camps, I'm gald you guys had a great experience. Certainly an individual thing. My sons enjoyed their camps at IMG too. In hindsight, we feel our $ were better spent on ACT/SAT test prep, individual baseball instruction, athletic training at other places (e.g., Athletes Performance), specific baseball instruction (e.g., Texas Baseball Ranch), college camps and showcases where my sons' targeted schools attended, etc.
I'd encourage anyone thinking of IMG, particularly for the wood bat leagues or for the full time program, to make sure they've done a cost benefit analysis. It is an extremely expensive place.
