DLP Parc is beautiful but really needs a fresh headlining dark-ride.
The only clones that really work for it that I can think of are Splash Mountain, Indy, TRON, Soarin', Pooh's Hunny Hunt, and Mickey makes by far the most sense.
I understand the decision, and as much as an Indy or Moana ride would be great, a headlining heightless requirement ride is what the park needs. Then, in the future, perhaps an Indy ride, who knows?
As for WDS, a Mickey ride would work better thematically, but from a logistics standpoint, with all going on in that park right now, and with the other park desperately needing a new ride as well, Mickey seems like a cost-effective choice. WDS could use a Toy Story Mania! to better effect anyway, or even Soarin'.
