Under Magic Kingdom and Epcot, there are "utilidors", which consist of complete roadway and walkway infrastructures.
They aren't tunnels technically because they're not underground. They are located on the ground floor, while the actual park is on its second floor.
Utilidors serve multiple purposes. They can be used to covertly move around characters, employees, food, waste, and merchandise. They can also be used for emergency purposes.
If you sign up for Disney Keys to the Kingdom, you can get a behind the scenes look at the utilidor systems. The five-hour tour is available for $99 when it's available. However, it's well worth the cost if you enjoy learning about Disney secrets.

Imagineers sought out feng-shui experts and masters while designing Hong Kong Disneyland. This ancient Chinese practice is about creating spaces that are in harmony with the natural world.
The Imagineers wanted harmony to be a part of their designs. So, when you walk through the park, remember that each building and walkway was designed with a greater purpose.

From 1955 to 1982, Disneyland guests and later Disney World visitors had to buy separate tickets for each attraction. Based on their popularity, the rides were divided into five tiers: A, B C, D and E in the late 1950s.
The most popular attractions were "E"-ticket rides. Disney did away with the system but the term still refers to the top-tier attractions in the parks.
Rides like Star Wars: Rise of the Resistance or Mickey and Minnie’s Runaway Railroad are today considered "E-ticket attractions".
