Geo-Location is a great tool for segmenting your guests. Use the Geolocation feature in creating segments based on guest location information found in your PMS or uploaded thought contact lists.
In creating your segments select the parameter Guest Location. Then choose from the first menu of options to distinguish if the location desired is within, is beyond, is in or is not in.
For locations using the option is within or is beyond. Enter in a distance and select if the distance is measured in miles or kilometers.
When uploading a contact list or segmenting based on geolocation the profile must include City, State, and Country. Note that additional location information may be included in the Rich Guest Profile but it may not be information that can be used for segmenting.
