Before making any serious decisions one way or another, it would help to talk to an advisor at the school in person! When I did my program, I got 6 credits–3 for taking one of the classes available there, and 3 for the program itself. This is because my school decided to count the DCP as an internship. I had to recruit a sponsor professor to assign me journal entries and a midterm paper and final paper, and keep in contact with me via Skype/phone throughout the semester. If your daughter's school gives credit for internships (as most do), they may give credit for the DCP. And if not, it's worth showing an advisor the list of classes available through the program, because some of these classes might count as electives, and some classes might even count as "equivalents" for classes at her school (I took a Communications course through the DCP that my school considered equivalent to a course required for my major).
I know some people who were able to actually remain full-time students (you need 12+ credits) by receiving credit for the program, taking a class or two on campus, and taking an online course through their college back home...this kept their financial aid completely intact, but was a major time commitment, so I'm not sure I would recommend it. Since I received 6 credits for my DCP, my school considered me to still be in attendance, but only as a part-time student–and so I paid tuition per credit that semester. I received no federal aid for that semester, and didn't have my scholarships either. It's a lot of money (especially if your daughter's school is private), and I did end up needing help from a parent to cover the balance.
This is probably coming out a lot more complicated than I meant it to, but ultimately...your daughter will still be considered a student at the school if she is earning credits for the program itself. If your daughter's school would award credits for DCP classes (not the program, but specific classes on campus), she could definitely take those and have the credits transferred back to her school while still being "on break" from school (and not paying tuition). If you don't want to pay part-time tuition, taking a "hiatus" might make the most sense in the long-run, and (like I mentioned) she could still get some credits out of the experience if her school accepts some DCP classes.
And if she does take the hiatus, your financial aid will usually be "stalled" and return to normal when you return to school the next semester. Once I returned from my DCP and went back to being a full-time student again, all my scholarships, financial aid and federal loans were reinstated (but I would ask, just to be sure).
