You could always study on campus/coffee shops/local libraries if you can't study at home. If you stay in Suwanee, you may have to sit the family down and have the talk about potentially missing events to study or having limited social time. That depends on your situation. Moultrie now is following Philly curriculum, Suwanee has had it's own, but they are trying to get all campuses on the same schedule (I don't know if that starts this fall).
Suwanee would have more general opportunities, but South will have 1 class ahead so you're not completely alone there. Moultrie is also the middle of nowhere which yes can be good for keeping you focused, but you will need time off. I don't know what they do down there, probably hang with each other for fun? Suwanee will have more academic opportunities, but also more social/outings so if you need that opportunity to blow off steam, then it's more readily available in Suwanee.
Plenty of people live at home. Personally, I moved out of a commutable home to live alone, so if you want more info on that feel free to DM me.
