If your daughter makes the Region ODP camp, I have been told it is the best possible camp she could attend. Great instruction, high-level training sessions and competition with and against some of the best players in the southeast. Your daughter will not be challenged like this at any college camp. This will help your daughter get BETTER and perhaps get noticed by one of the college coaches providing instruction IF your daughter is an ELITE player.
Now, if you would rather spend your money on finding out if your daughter is the proper fit for a school that she has already expressed an interest in attending, then surely your money would be well-spent in sending her to that school's camp so the coach can evaluate her (and vice versa).
