Anyone still in the queue, I recommend doing bag drop. When I was there it was almost completely empty, so if you've got the energy to walk quickly you can save time before the bit you're supposed cut back in. You do need a bag drop wristband to cut in though.
And overnight several older kids (7ish?) in buggies sleeping soundly, which are probably left so they're only really queueing 3hours from waking. Definitely didn't see any upset children at night.
