Our audience counts on Eventfinda to display absolutely accurate information about the events they wish to attend, so we insist on each event being displayed individually and not as a single listing at "various venues".
Each event with its specific venue, date and time should be listed individually so your attendees get the most accurate and specific information available. Nobody wants unhappy people who have tried to attend your event going home (and then online) disappointed because the information wasn't good.
If you're listing a tour, you can use the List Similar button which you'll find under your initial listing under the Advanced button. That duplicates the listing you've created so you can simply edit the date/time information, venue information, and if necessary any text differences.
