Hi
I flew from Stanstead last year and did one of those "surprise hotel" things, they usually flag up when you search airport parking, as it transpired, it was the Hilton, they lay on a very good shuttle service every 30 minutes all night and it included the car parking for the weeks holiday, cant remember the exact price but it was less than £100. So that was overnight stay, and the weeks carpark, I have a feeling I paid £79.
Had a lovely swim, steam and sauna etc at the hotel too, all in the price.
Not much locally food wise so drove about 15 minutes to the local town and got a Chinese, yummy.
ps we had to pay a whole £1 for the shuttle lol
