I live quite nearby and go most every year. It is a world class top notch event on the lawn of the lovely Ritz Carlton Amelia Island. Most folks consider it and Pebble Beach the top 2 Concours in the US. We've shown a few cars there over the years - and are showing our 1958 Cadillac Eldorado Convertible this year, so do stop by for a chat.
If I can give you any tips on the area, let me know. I would advise pre-purchasing your tix on line as saves quite a bit of time.
