We've found advance tickets for off-peak travel to and from the south coast from £5, each way, with Southern. The tickets are up to £17.50 cheaper than the regular price, giving you a little extra for fish and chips on the seafront.
This is the ideal excuse for a day trip or a short trip to Brighton, Southampton or Portsmouth from London Victoria this winter.
We found good availability in November and December, although you will need to be flexible to find the best prices. Tickets can be booked up to 12 weeks before travel, until 14 March, 2014.
Other routes are also available: Watford Junction-Eastbourne and Milton Keynes-Southampton start at £7.50, each way.
Railcards can be used on advance fares for an even bigger discount.
