TIP: use the LONGTERM carpark, for goodness sake... upto 1h: FREE / upto 2h: £1. (and use your common-sense by NOT staying over 2h, otherwise you'll pay the full day rate of £21.) It takes all of 10mins to/from terminal by fairly frequent free shuttle buses (though always leave extra time, in case of unexpected delays!). They do not want you to use the overcrowded SHORT and MID term carparks, hence why they have priced them accordingly, as discouragement. (incidentally, at time of writing, Stansted offer the same price, but at their *MID term* carpark!) Learn the new airport parking systems (most drop-off is charged now), ALWAYS give yourself extra time, then you'll not have the pain of paying through the nose.
