I'd personally move rocket lounge/deluxe diner into Avalon in place of some of the current food stalls if I was looking to make more space for Shangri-la/SE corner stuff.
Then when Avalon stage ends rocket lounge can start up. The diner guests can be treated to music whilst they eat.
New album from Self Esteem in April. Really hoping they might be able to get her for a slot on the Friday. She's booked for one or two other festival dates already.
