In the comments section of the DPB post about
MNSSHP, Shawn Slater said that "Villains such as Jafar, Cruella De Vil, Queen of Hearts, Lotso and Gaston will be available for character greetings during the Halloween party, at locations throughout the park." I assume they're moving Jack and Sally inside Storybook Circus so they can take advantage of the queue that is already set up there. We know where Gaston will be, it makes sense that Jafar will be in Adventureland, and Shawn Slater said that Cruella will be "near the train station in Fantasyland." That's where Jack Skellington met during
MVMCP last year (and where I assume Jack & Sally met at MNSSHP last year). That leaves the Queen of Hearts and Lotso. Honestly, I'm not seeing on the map Tiana's meet plus 3 others (for a total of 4) M&G areas on the map as Kenny claims. I see two--Tiana's regular M&G and one other. So I'm thinking that Queen of Hearts goes into the non-Tiana spot and Lotso is going to be near the MK entrance. Or maybe Lotso will be a wandering character (I believe this is what he did in the past) and the marker near the front of the park is for the Tremaines.
