Well, as you can tell from the updates it’s slow going at the zig zags!
in case it helps anyone: we got our wristbands around the London eye (so all of you would have to be there): plenty of benches/walls to sit before that point so easy to catch up with your group of you are with kids or just need a sit down!
Your group should also be altogether to cross over Lambeth Bridge & into the gardens (this is where wristbands get checked)
The zig zags are in 2 ‘sections’ : and they are just like airport check in. The mum & 10 year old just in front of us ducked out for a sit down in section 2 where there are benches & came back on the queue once we caught them up. I think that’s a good idea as it’s a good 90 min in that bit at least (see pic, it’s just a low wall but somewhere to sit at least)
I thought I’d overpacked with a blanket, hat & extra layers but I’ve needed them tbh even though it’s a dry & pleasant night
