Haunted Mansion will probably go down the Monday after Labor Day to get it's holiday install. Small World probably the second or third week (on a Monday) of October for it's holiday install. Matterhorn will typically go down in Sept for a refurb, usually either the day after Labor Day or the following Monday. Haunted Mansion is back up from the refurn and in NBC mode by the first of Oct usually. IASW will be up and running in holiday mode by the first weekend of November. They shouldn't need to do as long a refurb on the Matterhorn as it was down for over 3 months on the last one, but I'd say it'll be down for at least 3-4 weeks, possibly 2 months. My understanding is that the Matterhorn is getting new toboggans this time around, so testing them out on the track extensively will be required.
