It's a long time since I tried the train but the main problem was at the time, not having anywhere to store 2 big suitcases and two lots of hand luggage.
We had to stand in the aisle with many others for the whole journey.
Then, we transfered to some ridiculas shoppers type bus to go to the terminal.
Holding the suitcase out in front of you to climb through the narrow bus entrance and steps was a hernia sufferer's nightmare.
