 \-&nbsp;`station_area` <br/>*(added in v2.1-RC)* | Optional | GeoJSON Multipolygon | A multipolygon that describes the area of a virtual station. If station_area is supplied then the  record describes a virtual station. <br /><br /> If lat/lon and 'station_area' are both defined, the lat/lon is the significant coordinate of the station (e.g. dock facility or valet drop-off and pick up point).
 \-&nbsp;`capacity` | Optional | Non-negative integer | Number of total docking points installed at this station, both available and unavailable, regardless of what vehicle types are allowed at each dock. Empty indicates unlimited capacity.
 \-&nbsp;`vehicle_capacity` <br/>*(added in v2.1-RC)* | Optional | ID | An object where each key is a vehicle_type_id as described in [vehicle_types.json](#vehicle_typesjson) and the value is a number representing the total number of vehicles of this type that can park within the area defined in the station_area field. If the field station_area is defined and a particular vehicle type id is not defined in this object, then an unlimited virtual capacity is assumed for that vehicle type.
-\-&nbsp;`is_valet_station` <br/>*(added in v2.1-RC)* | Optional | ID | Are valet services provided at this station? <br /><br /> `1` - Valet services are provided at this station. <br /> `0` - Valet services are not provided at this station. <br /><br /> If this field is empty, it means valet services are not provided at this station.
+\-&nbsp;`is_valet_station` <br/>*(added in v2.1-RC)* | Optional | ID | Are valet services provided at this station? <br /><br /> `true` - Valet services are provided at this station. <br /> `false` - Valet services are not provided at this station. <br /><br /> If this field is empty, it means valet services are not provided at this station.
 \-&nbsp;`rental_uris` <br/>*(added in v1.1)* | Optional | Object | Contains rental URIs for Android, iOS, and web in the android, ios, and web fields. See [examples](#examples-added-in-v11) of how to use these fields and [supported analytics](#analytics-added-in-v11).
 &emsp;\-&nbsp;`android` <br/>*(added in v1.1)* | Optional | URI | URI that can be passed to an Android app with an `android.intent.action.VIEW` Android intent to support Android Deep Links (https://developer.android.com/training/app-links/deep-linking). Please use Android App Links (https://developer.android.com/training/app-links) if possible so viewing apps don’t need to manually manage the redirect of the user to the app store if the user doesn’t have the application installed. <br><br>This URI should be a deep link specific to this station, and should not be a general rental page that includes information for more than one station. The deep link should take users directly to this station, without any prompts, interstitial pages, or logins. Make sure that users can see this station even if they never previously opened the application.  <br><br>If this field is empty, it means deep linking isn’t supported in the native Android rental app. <br><br>Note that URIs do not necessarily include the station_id for this station - other identifiers can be used by the rental app within the URI to uniquely identify this station. <br><br>See the [Analytics](#analytics-added-in-v11) section for how viewing apps can report the origin of the deep link to rental apps. <br><br>Android App Links example value: `https://www.abc.com/app?sid=1234567890&platform=android` <br><br>Deep Link (without App Links) example value: `com.abcrental.android://open.abc.app/app?sid=1234567890`
