Coins tossed into water features & fountains are collected several times per year and are donated to Children's Charities in Central Florida.
Because of Florida's high water table, the park is actually built on the second floor. The first floor of the park are the Utilidor (all the tunnels where the non-magical things happen)
Characters only found in the Magic Kingdom: Gaston, Fairy Godmother, Anastasia, Drucilla, Aladdin (Jasmine is at Epcot), Rapunzel, Tiana, Tinkerbell, Elena, Arial, Cinderella, Merida, Peter Pan, Pooh, Tiger, Mickey & Minnie in celebration costumes
If you stay until park close there is a light show on the Castle called the "Goodnight Kiss" or "Kiss Goodnight" which is to send everyone on home
The water in the rides are all connected so if something falls into the water, good luck getting it back! (Another fun thing, when we were behind Splash Mountain there was a dead crow in the water tank but the ride was still in operation)
if someone dies in the park, they are not declared dead until they get to the hospital so no one has technically died at DisneyWorld...
