NCL Airport parking frequently seem to close about 50% of the long term parking car park (pending maintenance checks it seems), which forces customers into the furthest away elements of the car park and demands a bus ride (which is too infrequent). The perception is that they do this to force your hand and pay for medium-term parking which is adjacent to the areas closed. Whilst i understand the need for maintenance checks, it seems wholly unreasonable to close off the volume of parking spaces in question. A more staggered and equitable closure would be far better. Worth noting, this never happens in the medium-term car park which was re-surfaced at the same time as the area closed in long term parking. Simply doesn't make sense.
