Speaking of crowd management, having SNW open is going to create even more traffic for the soundstage location. Last year, there was always a bunch of traffic after getting out of the weeknd house, especially where the SNW entrance was. I also think that Nintendo wouldn't want to associate their family friendly land with HHN.No 9th house. Add SNW and Mario Kart to the grouping, you are going past the entrance anyways to get to Stage15 Venue.
