It is at almost every attraction. The ones that do no have it would be things you don't really need to wait for anyway.
What I can think of off the top of my head is:
Tomorrowland Transit Authority
The train at MK
Liberty Square River boat
Carousel
Carousel of Progress
Hall of Presidents
Swiss Family Robinson Treehouse
Tiki room
Tom Sawyer Island
Country Bear Jamboree
Ellen's universe of energy
The boat ride in Mexico
