Network traffic, including a device identifier, is received from an unrecognized guest device on a computer network of a hospitality establishment. A user profile server is queried to determine a user identifier that is associated with the device identifier of the guest device. A properly management system is queried to determine whether the user identifier is associated with a current guest of the hospitality establishment, and, when yes, to determine a guest area registered to the current guest. A login database is queried to find an unexpired login record of an authorized guest device associated with the guest area, the unexpired login record granting the authorized guest device access to the network service for an allowed access duration. The unrecognized guest device is automatically granted access to the network service for a remaining portion of the allowed access duration of the unexpired login record.
