Micello is a mapping integration which includes way-finding turn by turn directions around your conference venue and/or show floor.
All we need from you the client is a few maps of the venue/expo (PDF) hall to set up this integration. Speak to your Zerista account manager about the cost and timelines needed to implement this feature set.
Note: It is advised you also provide a google analytics tracking code to link into the maps to capture valuable analytics around how the maps are used at the conference.
