Ideally, TDO will greatly expand DAK's attraction roster, then close EE and replace the Yeti with a fully functional one. But they should've done that yesterday. Closing EE without any new attractions would have serious consequences for DAK's capacity, but it's better than nothing. And a couple years is a small price to pay for what will hopefully be decades of operating at full functionality. It's true, some people taking their once-in-a-lifetime vacation would miss out on EE entirely, but that's the way it goes with all attraction closures. If someone visited WDW in the summer of 2007, they missed out on HM, arguably a more important attraction than EE. Does that mean the 2007 HM refurb was "ridiculous" and "unfathomable?"
In either case, I think it would be appreciated if everyone could refrain from ad hominem and hyperbole when discussing this issue further.
