Gatwick - Redhill - Tonbridge - Paddock Wood, 1hr 27, £13.50 single, or Gatwick - London Bridge - Paddock Wood, 1 hr 24, £27.10

Fairly easy, change at Redhill and Tonbridge. You'll have to use the stairs at Redhill but there's lifts if you have lots of luggage, and the same is true of Tonbridge. Should take you around 60-80 minutes. There's frequent services between Gatwick-Redhill and 3tph from Tonbridge-Paddock Wood, but beware as there's only a hourly service between Redhill-Tonbridge. See if you can spot the tunnel of the Uckfield line around Edenbridge, took me a while to notice!
