I just thought of something. Do they drive on the right side or the left side of the road in Aruba? If they drive on the left side, is that hard to get used to when you live in the US? Would it be better just not to drive at all?
You have nothing to worry because it's easier to drive in Aruba. Drivers are always on the right side of the road that's why it's not a big deal if you'll use your USA driving license. It's very enjoyable to drive in Aruba.
