Exactly. Given the small number of attractions they're opening with, I'm not surprised the lines are long. I was rather surprised when I was on the DL HK website at how few attractions were available. But like all the parks, they will add over time.
Of course, back when Walt opened a park, that was because he didn't have the money to open everything all at once and oh yeah, he changed attractions often. Now, Disney has plenty of cash, I mean, they could afford Fox Family.
Still, it's a convient excuse to justify a worthless park that does nothing but dilute the brand.
