When you go to Snow White's Grotto, stand by the wishing well, every 15 minutes or so, the song "I'm Wishing" will play -- it's a special treat.
Disneyland is a "show" and the cast members are "on stage." When you enter Disneyland, notice the red brick - it's supposed to represent the red carpet. The posters hanging in the left & right tunnels are similar to movie posters previewing what you are about to see.
In Fantasyland, look above the Snow White Adventures attraction - you'll see a window w/a closed curtain -- the curtain will open and the queen will peer down at you. There is a brass apple in the queue as you enter Snow White's Scary Adventure --- touch the brass apple & something will happen.
In the Villains Shop in New Orleans Square there is a cage with a witch -- turn the key to the cage.
Star Tours stands where Adventure Thru Inner Space used to be ... when you are getting ready to leave the warehouse, you'll see a HUGE microscope. That is the one they used to have that the guests would go through when they were shrunk.
Every attraction that has been replaced has a reminder of that attraction in the new one. In Indiana Jones, it's the Eeyore sign in the queue - that was the section of parking lot that used to be there. In Star Tours it was Adventure Thru Inner Space. Winnie the Pooh stands where Country Bear used to be.
Walt Disney had an apartment that he actually spent time in while Disneyland was being built, and he would often stay there in the early days. This tiny apartment is over the fire station on Main Street. He used to slide down the pole, but they've blocked off the hole to the apartment there. There is a light burning in the window in honor of Walt Disney.
There were a set of apartments being built for Walt & Roy Disney in New Orleans Square. You can see their initials in the wrought iron of the balcony. He died before they were finished, and they served as offices for many years. They were then opened as a Disney Gallery showing original works of the Imagineers. It's currently being refurbished for the 50th anniversary. The balcony is now used for Fantasmic Dessert Buffet.
On Tom Sawyers Island there is a fort that is closed now. The fort used to have a nondescript door that when you went through it would lead you through a tunnel down to the river's edge. The tunnel is still there, but they've long closed off the exit from the fort.
The waters from Jungle Cruise, Rivers of America, Castle moat, & the area near Fantasia Gardens is all connected - one water way. The water near Fantasia Gardens used to be home to the very exciting Motor Boat ride.
The Matterhorn has two queues - the Fantasyland side, and the Tomorrowland side. The track on the Fantasyland side is a little smoother and a tiny bit longer. The Adventureland side is a bit rockier & includes a dip that the Fantasyland side doesn't have.
On Main Street, at gutter level, there is a pipe that emits yummy smells to entice people to go to the candy store. At Christmas, they pipe out peppermint smell.
At Coke Corner, there is a pianist who has played well over 20 years - his name is Rod Miller - if you have a chance, listen to him play. He's developed a little following, and they sell his cd's - very nice & talented man.
On Indiana Jones, on the actual ride, you'll go past a skeleton room. There is a skeleton on the left side, as soon as you enter, who has a Mickey Mouse hat with the name Bones on it. .... I've actually seen him - but only when I've sat in the back row of the car.
The queue for Indiana Jones has writing on the wall. There is actually a translation for the characters. When Indiana Jones first opened, every guest got a card as they entered the queue so they could decipher the writing on the wall. You can still look up the code on the Internet - it's called Mara's font

Tink33 still has her card & I still have mine.
