To take advantage of the best prices you will need to prove you are not a business traveller, on the way to gatwick airport, so you will need to provide either your flight numbers or yr holiday booking reference. I don't think you will need to provide this when you arrive at harpenden station but you may be asked to give them on your travels from harpenden station to gatwick airport.
Going to the airport on the train is great, you can sleep, read a book (even at night), play travel scrabble, or just gaze out of the window... The other restriction to buying these inexpensive train tickets from the station to gatwick 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 5 go free, and then one kidover five but under sixteen per adult travelling on the train to the airport.
make sure you leave plenty of time to get to the airport early enough to eat, shop and so on, so check the times of trains from the station before you go. If you have time to kill at the airport you can always read or play a game again! As you have bought your ticket in advance, you don't need to fret about the opening hours of the station.
the station opening hours: Monday-Friday 05:30-20:30, Saturday 06:00-19:30, Sunday 07:00-20:30, .
