Another interesting caveat, this year at least, was that the landing had to be paid in advance. Fair enough, but 'what if we can't come due to weather' i asked. 'You'll get a 50% refund' was the answer. I queried this but was told that was standard and they wouldn't budge.
So we have people overloading their 4 seat single due to the extortionate landing fee ( and I saw at least one small 4 seater off loading 4 large blokes), and then perhaps tempted to push on through poor weather as they will be 'fined' £100 for making a sound weather decision.
