"I am so very sorry to have to say that on February 22nd The Ziti sisters will perform their last show @ Epcot. I have never been so honored to work with such amazing women on stage and share a green room. The full time cast as well as the subs, are the most talented, kind generous, brilliant, motivating, smart, beautiful, seasoned, and uplifting women I have ever met. I absolutely adored working everyday. The staff, the costumers all of our managers, the voices of Liberty, the fife and drum core all made my experience working at Epcot one of the finest most happy times I've had in my life. Thank you all for being a part of all of this. It is time for the next chapter , with every door closed, another one opens.. The brightest rainbows are created by the hardest rains."
