OK Glenn, no problem, and thanks for letting me know.
The Holiday Inn Express is a good idea, especially if a family is coming over, and it'll be great if most forum visitors are able to stay there.
There's a good pub across the road, once used by air and ground crews form DX, and the location is very convenient for the airfield, being within reasonable walking distance, although there's a taxi company nearby if transport is required.
It's also right next to the rail station, so handy if a trip into London (or elsewhere) is included in anyone's plans.
Of course, like most places, the room rates are higher on airshow weekends, but it's still less expensive than staying in London or the city of Cambridge.
One thing I forgot to mention - the show ticket prices might be slightly better for a 'Group Booking', given the numbers are right, but of course this would be dependent on who and how many are going and when, ie both days, or one day, and so on.
