Disneyland has their own Fire Dept with a station located backstage east of Main Street and is dispatched by Communications Center at the park. I do beleive I've heard they operate a 2nd station at the newer park also.
Anaheim Fire provides paramedic and fire coverage also. Not sure about now, but recently Disney had been funding two medics units stationed near Downtown Disney, and heard dispatched on the normal North Net fire group 2E. Station 3 and 6 are the closest stations.
I have no info on what is and isn't monitorable at the 'Land'
