For us, Safari and EE (which they don't want to do) are the only things we bother to use our FP+ on at AK. DD(9) doesn't care for the Rapids(doesn't like getting soaked) or Dinosaur (frankly I don't care for Dinosaur either). We have FP+ Lion King and Nemo, but our FP+ have never seemed to fit in our schedule so we haven't actually used those FP+ . Unless they are going at a high crowd time, they probably won't have much trouble getting in those shows without FP+, but FP+ may get them better seats. The FP+ line enters first at LK (or at least it did last time we were there). I would say FP+ Safari, Lion King, and if they want to see it, Nemo.
