I have been in those tunnels. I worked a Disney back in 1982. There are costume changing areas for the characters, the workers have a huge cafeteria there. This is where the workers are.. then they go up to the areas where they work.

I did not see or feel anything nefarious in the tunnels.

Told the story bout mama going to sit in an area, and hearing a child wailing from the tunnels. She told "security" they said NOPE not possible. She insisted. They said "oh service tunnels" She said not just crying WAILING. Said "I have three kids, I think I know the difference between regular crying and WAILING" Dude threatened to have her escorted out. He backtracked to the "probably some employees child just crying a little" She said that baby was WAILING this is when I was super little, like for sure the seventies, earlier seventies.

I read a story about how They used those tunnels to steal children in the park
