East Worthing has cctvGatwick, London Gatwick Airport, Gatwick, West Sussex, RH6 0JH.
To take advantage of the best prices you will need to prove you are a leisure traveller, on the way to gatwick airport, so you will need to provide either your flight numbers or your holiday booking reference. I don't think you will need to provide this when you arrive at the station but you may be asked to provide them on your travels from the station to gatwick airport.
Going to the airport by train is great, you can take a nap, read (even at night), play a game, or just stare out of the window... The other caveat to buying these inexpensive train tickets from the station to the airport is that there must be at least two grown ups travelling together. But another great benefit is that children go free. All children under five go free, and then one child over five but under 16 per grown up travelling by train to gatwick airport.
make sure you leave enough time to get to the airport early enough to eat, shop etc, so check the times of trains from worthing station before you go. If you end up with time to kill at gatwick airport you can always read or play travel scrabble again! As you have bought your ticket in advance, you don't need to worry about the opening hours of the station.
