If you are paying out of pocket I would take the courses that will all go towards your business degree. An AA won't get you a job, so I wouldn't be too concerned about random hours to fulfill those hour requirements. Why pay just for hours? Full time in the summer is 6 hours most places, 9 at some others. Assuming each course is a 3 hour course, you are looking at 15 hours, which is more than full time for a traditional 18 week semester. I have taken 6 hours the last few summers (grad school, 9 hours is full time fall and spring) and it's challenging with a small child. You know that though! As long as you have the support needed to take all the courses and are aware of the difficulties than go for it. Online courses (I both teach in an associate degree program and attend grad school online) require you to be much more self motivated. It is incredibly easy to get behind and struggle to catch up. If you can do it, then go for it but if you are unsure I wouldn't risk spending money on courses you may have to drop later. Good luck with whatever you choose!
