My kids watch a ton of Disney, but we just buy the movies on Amazon streaming rather than show them whatever happens to be streaming on Netflix. That way we can download them for on the go travel.

Right now we have Netflix, Hulu Plus, Amazon Prime Video (comes with Prime so not really a separate thing), and HBO Now (just for GoT season). I don't think I can justify yet another service. And I'm a parent of 3 year olds!
