1. A computer-implemented method to provide combined alert notifications, comprising: determining, by one or more computing devices, a relationship among two or more points of interest; associating, by the one or more computing devices, the two or more points of interest in response to determining the relationship among the two or more of the points of interest; communicating, by the one or more computing devices, geofence boundary data to a user computing device for a clustered geofence boundary encompassing the two or more points of interest, wherein the user computing device is separate and distinct from the one or more computing devices; determining, by the one or more computing devices, that the user computing device has entered the clustered geofence boundary; and providing, by the one or more computing devices, a combined alert on the user computing device regarding the two or more points of interest when the user computing device is determined to be within the clustered geofence boundary.
