Interesting. I don't get depressed about the yeti, because I would rather go to WDW with a static yeti than not go to WDW.
While I understand what you're getting at, it's still kinda a cop out with what you're saying there. Yes, I'd rather go to WDW than not go at all, that's a given. But....
I'll preface this statement saying that I'm not an AA engineer, but I am an aeropsace engineer and have higher business graduate degrees and I see every corporate situation through a "green" shaded lens, i.e., money. It's all about money, that's what this boils down to. Fact is, EE is the major, albeit only ticket draw for AK. Without it running, the park would have a quarter of its attendance than it does now. Other rides in the park are okay, and the safari is fun, but there truly isn't anything in the park that'll keep people in the park longer than 3-4 hours.
And while I like zoo atmosphere, and it's great to experience that adds to overall theme, there are detractors to the park that outweigh staying in there for a full day. 'Dinosaur' is pale in comparison to its cousin Indiana Jones at DL and is in need of major updating and is almost not worth riding, and 'Primeval Whirl' is (aka Mulholland Madness aka Goofy's Sky School) very limited fun for anyone over 6 years old. The accompanied land that those two rides are in is just plain awful. It feels like you're walking onto the set of Flintstone's part 2, cheesy and cheap.
So, I assume that either a) EE needs to be completely shut down for troubleshooting purposes that would take longer than a 3rd shift lasts, and/or needs a lot of test and check equipment set up that can't be hidden during park hours. b) TDO doesn't see any ROI for fixing the ride, considering that the ride isn't seeing a dropoff of ridership with Yeti broken (because 95% of the people riding it probably haven't a clue that its broke). c) TDO is indeed waiting for the scheduled EE refurb, whenever that may be.
When I visit in December, I will be going to AK and will be riding EE, and it will still be fun. The bad part is that the rest of the group I'm going with might not ever see the ride the way its supposed to be originally enjoyed, leaving me to explain how its supposed to be, which is a shame.
