The deepest pockets.
I'm a big fan, having worked for the company for ten years.
But let's face it. They have the billions of dollars it takes to have the best costumes, the best sets, the best everything. They should have long-running shows of the highest quality. There's no excuse not to.
That being said, however, when one of their shows doesn't strike a positive nerve with audiences, those same billions are so deep that they can even absorb the shows that maybe don't do "as well" as others.
I liked Aladdin. But I also liked Aladdin at Disney's California Adventure. The carpet actually flew out over the audience (until it malfunctioned, well into its run, and was largely put to bed). And the guy I saw play the Genie was fantastic. Personally I thought he was just as good as Iglehart, just a different take on the role.
The theme parks of Disney put on such great shows that I'll always be somewhat interested in seeing how they translate some of these shows to Broadway now. From the ones I've seen I would describe them as the theme park shows on steroids. They have to stand out, of course, because it's Broadway. And Disney has the billions of dollars to make that happen. So it should happen.
Sometimes they misfire a bit, but the billions are there to cover that too.
