Punki: If you are flying BA, it is much easier to get BA to sort out your accom needs, they have obviously have some of the best deals with the airport hotels.

As Efrem said the Heathrow Hilton is a fine (although it is impossible to get a really cheap deal there). The new Marriott has also recently opened at Heathrow, it is a very pleasant hotel. In my view by far the best hotel at Heathrow is the Edwardian International, they will provide hotel-terminal transfer.

At Gatwick the Hilton is OK, but the Forte Crest (or whatever they are calling it this week is better).

If you plump for the Hilton at Gatwick, you should be able to get a Corporate rate of £90 per-night weekday. For the Heathrow Hilton, you are looking at a minimum £120. If either of these properties offer you "run of the hotel" rates , don't consider it of any benefit. Both Hilton's have Clubrooms.

But the best advice I can offer is get BA to arrange the accom, they usually recommend the Forte or Hilton at Heathrow or the Ramada or Hilton at Gatwick.
