Many college coaches nowadays are looking at players that attend their camps on the college campus. They no longer as, a general rule, go on the road except for HUGE college exposure showcases. For a rather local tournament, within a 45 minute drive or so, that's a different story.
College coaches do not have unlimited recruiting budgets like football, so coming to a coaches camp shows genuine interest in the school and will at least guarantee that the coaches get eyes on your DD while she is there. That said, coaches still recruit talent, and the early verbals require coaches to do a lot of speculation on future abilities.
