This Skeleton Key has been around since Planet Coaster.- Making a staff or guest path from a que path. Place a que path, click on the entrance pillar and delete, switch to a regular path
and use that to fill the gap, continue until done. A piece of staff path at the entrance prevents guests from travelling in staff areas. Various applications for this include narrow paths between habitats and restricting keepers to back access of exhibit arrays when
not connected to guest paths.
