Halloween refurbs - consistency between years?

[losfp]

Does anyone have any links to historical Disneyland attraction refurb schedules? We're looking to do a cruise to Alaska in August/Sept next year (26/8-2/9) and will do Disneyland before or after - just trying to see if there's any consistent time they bring down IASW, HM, JC etc for their holiday refurbs so we don't visit when half the park is closed down!

Here is a thread with links to the wdwinfo calendars for DLR:

IaSW and JC don't normally close to have a Halloween-overlay installed; they close to have a Holiday overlay installed. So in late August and early September, only Haunted Mansion and Space Mountain may have closures to have their Halloween overlays installed. While there is some consistency between years, it really all depends on when HalloweenTime is slated to start. They usually don't announce anything to do with HalloweenTime until mid-summer. Usually HM will close 18-days before and Space will close the 4-days before the start of HalloweenTime.
