If you miss her at Tusker, she does ONE HOUR of meet and greet still at DAK. From 12-1 in Camp Minnie Mickey. She visits guests for that hour in the same kiosk you will usually find Donald. But I mean it when I say one hour and one hour ONLY. Be there at noon or earlier to get her. The closer it comes to one, the less a chance you will see her. She leaves at one and does not return to animal kingdom the rest of the day.
If you miss her there, she does FIRST THING at Studios at the hat. The problem however is she meets guests with Minnie and the line is usually so long it's closed before they even come out. She is only there a few hours in the morning. It's more of a hassle then it's worth at that location.
Best spot is actually Magic Kingdom Town square area. Check the times guide for the meet and greets in that area. The last time I came down to work, that area was from park open until about 2 in the afternoon with some off and on time for the "Move It, Shake it" show times. I don't know where she stands anymore. Last year, when I got my picture with her, she was by the fire station, but I think she MAY have moved to the other side.
Best bet, first Character Attendant you see in Magic Kingdom (we now wear blue shirts with light tan pants, no more black white and yellow)... ask where and when you can find Daisy. Hope you find her.
