We all know holidays end up being pretty expensive, especially when you factor in accommodation, spending money, the pre-holiday clothes shop... and that's not even including your flights.
But as ever, there are some hidden costs which mount up to a fine penny.
You might think you're being clever by driving your own car to the airport and opting to park it there while you're enjoying your time in the sun, but you may choose the expensive taxi ride next time after reading these findings.

On the other scale of the spectrum are airports in Bangkok or Düsseldorf where you’ll pay over eight times less than this for the same period of time.
To calculate the rankings, the index obtained the cost of parking for a week at each one of the world’s 100 busiest airports, based upon passenger traffic.
The prices were collected in local currency and then converted to British pounds, US dollar or Euros.
It's based upon parking for one week, without prior booking at each airport’s official car park.
