And they use the buildings from the first event to provide for the 2nd event...which is why there was probably a reduction as well. The 2x2 will give more pax, and the 1x1 are more like tiny fillers that give drops for the 2nd event. They want both buildings to provide pax, but each set of buildings provide drops for different events.Just to add on, that is probably why they decided to do both events this year. The passenger buildings wouldn't have been enough to do many flights. They had to offer A Walk in the Clouds first.
