I'm off to the Netherlands this week-end, flying from NWI.

Just tried to book my car parking on the NCP site (pre-booking is supposed to be cheaper!) and was amazed to find the web site was trying to charge me GBP 28 to park my car for less than two days - which is a LOT, especially for little Norwich.

Just out of idle curiosity I then got a quote for three days... and it went down to GBP 23!!! For four days it goes back up to 28, which is roughly what I would expect.

I suspect this is a bug, and have reported it to NCP, and I hope that they will fix it... but in the meantime I'd advise against pre-booking for short trips!
