Disney is ramping up its preparations for the arrival of Fay. So far, no announcements as to when or if parks are closing. In the past Disney has chosen to be overly cautious when the resort was show to be in the path of an oncoming major storm. They will often close the parks in the morning with the option to open them later if the storm damage is light.
Stay tuned for further announcements later today either here or at The Orlando Sentinel.
