I think this is the issue. Folk not going to dance but to do a circuit checking it out. Usually you can find a venue with a bit of space as long as you're not *too* arsed but seeing a specific DJ.
Arcadia was the same when we went on Sunday night. Felt like we were the only ones having a boogie.
Could a partial solution be to have some of the SEC stages open earlier?
IIcon, Genosys, NYC Downlow - generally start at 8pm, Temple at 10pm, various others at 8pm-ish.
Could having them running from midday each day, especially Thursday, let some people get the SEC "out of their system" instead of going there after midnight?
Do people shuffling through Shangri-la/Unfairground for a gawk really need to do that at 1am on Fri/Sat/Sun?
I know it's not going to solve the problems, but it might make them a little less acute....
