I've been meaning to post this for a while, but was left too busy with university to do so until now.
I have a spare bed available for 3 nights at the Crowne Plaza Docklands from Friday the 26th to Monday the 29th.
The cost is £150 (cash-only) for all three nights and the bed itself is a single bed.
I've stayed at the hotel itself for practically every Expo since October 2010 (the only exception being the May 2011 one) and I can guarantee you that it's a good place to stay in (That, plus it's only a 5-minute walk to ExCeL itself AND there's quite a few places to buy food and drink on the cheap including a Tesco Express with cash machine that's about a minute's walk away!
If anybody is interested or has any further questions, I can be reached by email which is rune [dot] jayce [at] gmail [dot] com or via Facebook (my Facebook page name is "HenshinJayce")
