She says she's been thinking about this for about a year and finally decided it was the right time. She will remain with the festival for three more months and help the search committee find a replacement.
In a blog post, she wrote: "So many will ask why, and my only answer is why not. I never intended to run the Festival and always wanted to get back to doing my own thing. It is time. I am ready."
She plans to relaunch her boutique public relations, but says she will remain involved in the festival as a volunteer and will do whatever she can to support its future success.
