Walt Disney World has updated it's official site, including its page for The Jungle Cruise. Notable updates from the previous version include more recent photos that include the currently-in-use boats rather than the classic striped-canopied originals that were still used in photos on the site up until last week, and a nifty sepia-toned newsreel style video promoting the attraction. Much as I prefer the original boats, it make more sense for the site to match what's currently on the attraction.
I think that the Disneyland version has stayed mostly the same, but I thought it used to rotate through a few photos, rather than just the static image of the sign. My memory might be foggy on that, though.
