how much is train from Brighton to Luton, can you do a 4-2 deal and is it possible to get back after bearing in mind it could go to penalties
You can get a 4 for £30 ticket from One Stop Travel in the Old Steine that lets you travel to Luton and back on FCC. However you may struggle to get a FCC train all the way back as they stop running between St Pancras and London Bridge after about 10. You'd probably be ok on Southern at that time of night but up to you.
Also you'd have to queue for ages behind loads of fuckwits in One Stop Travel.
