The biggest challenge was presenting the multi-day, parallel programmes in a logical and user-friendly way. We had to create a schedule that is clear, quick to understand and easy to use, even when events in several rooms are running at the same time.
It was also essential that all of this works perfectly on mobile, since during the event most visitors check the current programme on their phones. So the programme structure had to be designed so the relevant day, time slot and room can be found quickly on a small screen too, without unnecessary scrolling or "table collapse".
On top of this, the exhibitor section had to be built twice: a public exhibitor page where listing the exhibitors is the main goal, and a separate VIP area that also shows what discounts each exhibitor offers users. The challenge here was that the two areas had to share the same underlying data structure, yet appear with different permissions and content.
