We at Neatorama love Disney and have featured a lot of trivia about the Disney parks, but even with all the coverage we've done, I was happily surprised to see that this cool Travel and Leisure article actually had quite a few facts that even I hadn't read about yet.
For example, did you know that the clothing worn by the presidents in the Hall of Presidents not only looks period appropriate, but were even made in a period appropriate manner? Or that the Disneyland Railroad is ran on French fry oil? And as for those pesky wait times:
Cribbing a page from airlines’ standard operating procedure about flight times, posted wait times for rides are intentional lies. According to a Walt Disney World cast member on a seven-hour Backstage Magic tour, management overestimates by five or 10 minutes so that guests are "pushed" at different areas while also coming away from rides with a warm impression of exceeded expectations.
