While you received a lot of flak for this, I'll rush to your defense!
WDW doesn't operate as a whole. No, DAK is operated as a seperate entity. With a vice-president solely responsible for DAK. If Michael Colglazier (DAK vice-president until last month) had closed Everest for six months in the three years he had been DAK vice-president, then indeed guests would've simply gone to the other WDW parks instead. BUT...DAK's attendance would've taken a major beating, and DAK would not have been the park that in a complete surprise move overtook DHS to become third park in Orlando - which it did under Michael Colglazier's watch. And he woudn't have been made president of the entire DL resort on account of this spectacular result.
This is why nonsense such as is the sorry state of Kali happens. The man responsible got rewarded for it. The other vice-presidents at WDW all have taken notice: TWDC promotes those who increase the numbers of their own unit, and do so in the short term. Unless you want to be the village idiot, a WDW manager knows: the good of the whole or of the long term be damned.
