I wonder where they could set up a second stage without creating an absolute bottleneck in what is already the most cramped artery for the event. The Lagoon show in 29 was wonderful, and while 30 was a spectacular dud, I really enjoyed the show last year too! It'll be a shame to lose the lagoon, especially if ST is indeed happening.
Last year was the best year for zones in a long while, and part of that was giving each of them room to breath. Throwing up another AoV-esque stage by Mels would be really unfortunate.
