We got to London Bridge at 8.30pm, joined the queue at 9 & currently v close to Westminster (the Palace Gardens zig zag bit)
Think will be less than an hour now
Queue is super well organised, loads of police, plenty of loos, some places for coffee & snacks (after an hour or 2, not loads)
No point taking chairs (there are benches/low walls of you need a few minutes off your feet)
Bring layers & food - but seems we have to throw away anything not eaten at the end
Ideally I would have come in the day but London at night is v peaceful/makes the time go faster
Not excited about making my way home to London outskirts at 3/4 in the morning though so if you’re coming at night maybe 10 or later would have you out at 5-6 with tubes running
