destinationHash property
The hash identifier for the Destination on which this Activity is played. Use it to look up the DestinyDestinationDefinition for human readable info about the destination. A Destination can be thought of as a more specific location than a "Place". For instance, if the "Place" is Earth, the "Destination" would be a specific city or region on Earth.
