You should take her to the ladybug release at GF. They used to have a butterfly release somewhere on property but cant remember where it was. You might want to call Gst Relations.
Have to say WDW has several wonderful butterfly areas. Two in Epcot (TT & UK), one at the Beach Club (lobby back exit), GF (to the left of the front door). I was so pleased when they built a replica of the CR to house the butterflies at their resort and FW is always filled with Butterfly plants.
