While the response may be late, maybe it helps some in the future.
I use Galaxy Self Park (right next to Roncari). I find a spot in the first 2 rows 99% of the time, they pick you up at your car (will wait if they see you) and have regular outbound. I've never had to wait more than 3-4 minutes before being en route to terminal. Their pickup time tends to be a little slow and you may have to wait an extra few minutes, but they do drop you off at your car and will help clear it. They always offer to help with baggage and have a really cheap AAA rate.
