I'm a bit puzzled by that. From q-bot last night, it went from 9.5 hours to 14 in 30 mins, with the queue ending in the same place. Either they made another snake area or they just changed estimate. Are you relieved? If not, you could still try it. Looking at Tweets, no one has taken longer than 9 hours though I realise that could change by the time you get there.
I have to go towards town later and thought I could walk along the North Bank to see the bridges lit up but that would mean waiting about 2 hours and I cba. If there's a queue to see the queue, the North bank will be rammed anyway.
twitter is so good at times like this!
