Disneyland used to do something unique. Rides were integrated with each other. I always thought that was so cool. Moving forward, will DL continue this tradition? Somehow, I doubt this. That's sad. Anyways, some examples:
PeopleMover running through ATIS/Star Tours queue area.
PeopleMover "spying" on Space Mountain riders.
PeopeMover running through CircleVision queue area. (Note how the PM was always running through something or above you. It really made the land alive! See a pattern here?)
Train running through Splash Mountain
Train running through IASW facade
Casey Jr running through Storybook
Skyway running through Matterhorn
What else am I missing here? (Both past and present)
