You might consider asking to change your first leg to the day prior and suck up the overnight. Of course, it means you have to take your bags and re-check them in the morning. And since this is 1 minute above the MCT, they may not be willing to make that change. It's basically insurance that you'll get the Aruba flight by paying for an overnight before the flight or, potentially, having to pay for an overnight when you misconnect (as well as the hotel first night in Aruba that you won't be checked into).
Another option - not sure where you're originating, but would you be able to make it to CLT with a better connection buffer? In October, there's 2 daily flights most days - 925am and 1125am.
