Select or Invite- limited to older campers who are recommended or invited. Emphasis is on competition. Often many college coaches attending. Good chance to gain interest from a school. If you can get invited and make some noise, you are in good shape.
Many camps offer a form of financial aid in the form of work detail- usually in the kitchen.
In other words, if you want to work extra on your skills after dinner, you should not have to look far for a coach to help you out. Other things to remember Who is coaching- if your primary reason for attending a camp is skill development than it should not matter how many college coaches are there. While it is nice, high school coaches can be superb technical instructors, as good as college. You can get superior instruction at local camps with youth and high school coaches. If you go to select camps or with the idea of getting in front of college coaches you need to qualify in advance how many will be attending, for how long and from where.
