In reply to mutt:
Honestly, you'll probably be better off just queueing. It'll be grim early in the morning.
Someone will jump on it any time it's free but there's so much else around that not many people will wait for it to become free, if that makes sense. So if you've got your heart set on it you might have to wait, but you'll most likely be the whole queue.
Getting parked, however.......
