All the direct trains go to Victoria so you don't have much choice in that matter. However you will qualify for Groupsave and if you buy Travelcards at Victoria Station ticket counter opposite platforms 14/15 you will also qualify for the offers on daysoutguide.com. If you are staying two weeks then buying weekly zone 1-2 tickets will save you even more money
Normally you should qualify for the offers because you are travelling by train but there is some question as to whether Groupsave tickets qualify
No need to buy the train tickets in advance as they'll cost the same if bought on the day. You might find that a short term season ticket might work out better though I'd doubt it.Edited: 04 March 2012, 19:20
Victoria is the only direct train option (apart from on weekdays there a 2 very early morning services in to London St Pancras via Blackfriars and other stations in The City, and one return service from there in the late afternoon rush hour).
If you are travelling off-peak and all together, you can buy a GroupSave ticket where 4 travel for the price of 2. (You could share the total cost amongst the 5 of you to make it fair).
If you buy a One Day Travelcard from West Malling station then this will incorporate unlimited day travel on London's Underground and buses as well.
When travelling by train there are 2 for 1 offers http://www.daysoutguide.co.uk/2for1london or pick up a leaflet from the train station.
You can view timetables and check for engineering works at the train operating company's website http://www.southeasternrailway.co.uk/
For a general journey planner, it's normally easier to use the National Rail website http://www.nationalrail.co.uk/
For your journeys to London on weekdays, make sure you travel after 09.30 for the cheapest fares. There are no time restrictions at weekends.
As explained above, GroupSave will work for 4 of you, obviously leaving one person to pay the full fare. If one of your party is under age 26 it might be worth their while purchasing a 16-25 railcard. The cost is £28 and will give a 1/3rd off all fares. They will need a passport size photo. nationalrail.co.uk/times_fares/railcards-dis…
You might also consider travelling in the opposite direction to London, as there are a number of places of interest in Kent. By train these include: Canterbury, including its cathedral; Sandwich and Broadstairs for the coast; Dover castle and secret war time tunnels; Walmer Castle and Gardens; Deal Castle; Rye (historic port town). Each of these require an easy change of trains at Ashford. Within walking distance of the station at Ashford is a designer shopping outlet. http://www.mcarthurglen.com/
If travelling by train or bus, there are 2-for-1 offers at the places named above (panel to the right of this link): http://www.visitkent.co.uk/default.asp
Let us know if you will have a car for part of your stay as there a range of other places you can easily get to.
One little point to clarify ST's excellent information - I think Group Save is available only on off-peak fares.Edited: 04 March 2012, 23:43
groupsave is valid on travlecards
Thank you all for your suggestions
If I travel from West malling to Canterbury by train , will I be able to purchase the Canterbury Passport tickets as well? Do I have to buy them before or when we arrive there? thanks for your help because your response is helping me to plan my holiday.
Thanks for our suggestion to contact Canterbury forum. Their reply was very helpful. Now I'm plannning my trip to Sevenoaks & Chatham. I need your help to find the right connections to get there from West Malling. I wish to travel with southeastern because I've got 2 for 1 vouchers for certian attractions & I've got to present the train ticket.
Thanks againEdited: 18 May 2012, 16:42
West Malling to Sevenoaks - a simple journey with one change at Otford taking 40-45 minutes. Twice an hour
West Malling to Chatham - more complicated - the quickest is just under an hour changing at Swanley.
But the cheapest route is to Maidstone East, walk to Maidstone barracks then change at Strood - takes a little over an hour.
Both routes hourly. All South East trains
