^^ That's partly true, but only for certain attractions. Here are the reasons...
1. The holiday overlays allow short-term refurbs that have to happen anyway. The attractions would be closed in October and January, which is when most refurbs already occur.
2. Some overlays barely require any time at all, such as the CBJ Christmas show.
3. I agree that HMH is overkill, especially since the movie's demographic isn't nearly as widespread as the classic HM's. I suspect that many of the international Guests visiting WDW have never seen NBC and wouldn't know what was going on. IMO, Disney could still decorate the HM a little, with ragged wreaths, tattered garlands, and even a ghostly Christmas tree in the ballroom. This could occur overnight.
4. There is NO reason not to run the Christmas parade earlier than Christmas week, except to sell tickets to MVMCP.

I've stayed out of this discussion, but I'll finally pipe in (not that anybody cares).
Slash and Burn is in effect right now because of the economy. Most of the park leadership is ridiculously short-sighted and they're not planning for long-term returns. But the whole place isn't falling apart, and I don't think WDW1974 is saying it is. Refurbishments are going forward as planned, the Space Mt. refurb is longer than expected, and new attractions will eventually dwindle down to the parks. WDW existed perfectly fine from 1971–1982 with only about two significant additions to the MK.
The problem is that everything being done has already been planned, and park execs are so short-sighted that they aren't properly planning for the FUTURE. That's what has WDW1974 and a whole lot of other people very concerned. Most of the cuts are affecting the MK, too, which needs refurbishment and refreshed attractions more than any other park.
I don't think anybody expects Disney to dump money into the park during our recession. We just want them to be ready for the economic rebound.
Food for thought: if Disney would have invested into the MK properly for the last twenty years (let's say one more E-ticket, two D's, and possibly a C or B), none of this would matter right now because the park would be able to sustain refurbishments and economic-minded cuts without affecting Guests too much. In other words, it would be more like DL.
