I am planning a UK visit next year and part of my schedule meant I was arriving late into T2 on an Aer Lingus flight. Quick search on the Hilton website and this beauty turned up with a flexi rate of GBP74 for the night. Billy Bargain. Can't work out where it could be located (I have only ever flown out of the new-ish T2 in darkness - very early or very late so have no idea how it sits within the central area). Walking distance, no shuttles or Hoppa's is a great bonus.
