I was disappointed that Haunted Mansion might have been down for my last visit. It opened early, which was wonderful for me. That said, I was split on the closure.
For me, it was all good, I'd just see it on this year's visit. For one in my party, I was more disappointed because it could have been his once in a lifetime.
To an end, WDW just needs to get folks used to long closures. If everything were closed for long closures consecutively, there will always be one serious closure with most else open. Short closures just aren't a big deal.
I sort of think the Yeti may move again toward the end of the decade after the Avatar attractions distract guests. That is if they haven't totally written it off as just not worth it. The average guest has no idea there is anything wrong.
