One venue, several March fairs
TIF-HELEXPO confirms the dates and venue and says Infacoma will run alongside Forward Green and Renewable EnergyTech. The Documentary Festival also overlaps in the city, but its programme is centred elsewhere; check each organiser’s timetable rather than treating them as one event.
Pick a base for your actual itinerary
For repeated exhibition visits, compare the eastern centre near TIF-HELEXPO. If film screenings are also in your plan, compare the centre and port area against the daily trip to the fairgrounds. Verify registration, entrances and transport closer to departure.
