I have just returned from DLP and all I can say is that although there are mostly organised meet and greets there are still the odd one or 2 randoms at the moment, like Mary Poppins and Bert with a penguin, under the gazebo on Main Street. Jack Sparrow has been seen out by Pirates of the Caribbean gift shop. Suzy and Perla sometimes come out opposite the teacups before going back in to Auberge de Cendrillon and Pinocchio and Gepetto often hang around the big gates next to Its a small world, even though they are not an organised meet and greet! I also happened to wander down towards Casey Junior last Friday and I came across Aurora, meeting and greeting guests and Merida was there too even though she is not supposed to be out yet! its just look of the draw!
before I went Belle in her little town outfit and Gaston had been seen in the studios. if you can, check ED92 live on twitter or DisneylandBerry as they often tweet live from the parks and catch rare characters in action!
