Warwick Parkway has cctvGatwick, London Gatwick Airport, Gatwick, West Sussex, RH6 0JH.
To take advantage of the best prices you will need to prove you are not a business traveller, en route to gatwick airport, so you will need to give either yr flight numbers or yr 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 give them on yr journey from the station to the airport.
Going to the airport by train is great, you can sleep, read a book (even at night), play a game, or just stare out of the window... The other caveat to buying these cheap train tickets from the station to the airport is that there must be at least two adults travelling together. But another great advantage is that children go free. All children under five go free, and then one child over five but under 16 per adult travelling by train to gatwick airport.
be sure to leave enough time to get to gatwick airport early enough to eat, shop and so on, so check the times of trains from warwick station before you go. If you have time to kill at gatwick airport you can always read or play a game again! As you have bought your train ticket in advance, you don't need to worry about the opening hours of the station.
warwick station opening hours: Monday-Friday 24 hours, Saturday 24 hours, Sunday 24 hours..
