Kenny the Pirate's site is great as mentioned above, but you do need to subscribe for more specifics - only $10 I believe, well worth it IMHO to have easy reference for times and spots. Steve Soares' site, wdwent.com, also has a good list of characters at each park and entertainment info. Definitely see if there are some faves she wants to meet, as certain characters are only available at one park, like Olaf at HS , Gaston at MK, Baymax/Anna&Elsa/Joy&Sadness at Epcot, or Russel at AK, so you want to make that a part of your plan, as opposed to others who are at multiple parks, like Mickey and Minnie who are at all parks, or Donald at all but HS(other than H&V meal). As PP said, Gaston is so funny - he gets long lines, so best to line up before first time of the day(usually starts at 10), or after his afternoon break - best to line up about 1/2 hr ahead for him - line is behind his tavern. You could also see if she'd like to get autographs, so you can get a book before or at the parks and bring a Sharpie.
