We like both too! Both are on our list for every trip. While we love CM dinner, we love TH breakfast. Both are so fun! We have never had a bad experience at either. CM has Mickey, Minnie, Donald, Goofy, and Pluto. TH has Donald, Mickey, Daisy, and Goofy.
Would your DD like to see Minnie and Pluto or Daisy? I'm not sure if Daisy is still meeting in the parks, but I know you can see Mickey and Minnie together, in their safari gear, at Adventures Outpost in AK. As far as I know, this is the only place you can see Mickey and Minnie together and you can get a FP+ for this meet. And Pluto and Goofy meet together in Dinoland USA, in AK, at the gas station. There is no FP+ for this meet.
