It is. If you have no bags to drop it’s better than any car park at the airport as the monorail runs every 2 mins, is free and drops you into the entry of departures security. The price is cheaper than turning up and paying to park in the best car park though can’t speak about the further away ones as never use them.@Housey - is that the car park at International Station? Seems convenient if so and the kids love a monorail! The Korean bus would probably ruin the aesthetic judging by your photos though.
