IMG is a beautiful facility. With that said though, here is my take...
This is a really expensive program. While you may get some "scholarship kids", most are paying full cost. So, while you may very well get some talented players - you are also going to see some that are there because their parents can afford for them to be there. Now, you are going to get good coaching in a good facility - but there's no guarantee of how good the players around you will be.
Again, I'm not saying there aren't good players there - from what I have seen there are. It's just that you are really talking about the ultimate pay to play situation. It's really potluck on who you could be playing with and against.
In my opinion, I think you can find quality summer ball in your area without spending nearly as much money. I know the Tri-State Arsenal plays out of NJ, and that program has a pretty good reputation. I'm sure others here can offer up other programs as well.
