Thanks corrigin (any relation to the memorable Bruce?) for that. I have gone for Arfur's IdDeals which has a good layout and easy to operate. And I don't mind paying a few quid for a site that can save me time, effort and money.
We'll see how accurate it is when I use it in a couple of weeks for an LH ticket but I think all these ID information sites all use Abacus or Sabre anyway and sell hotel rooms to pay for it. Works for me.
