can i pls check if i want to buy an off peak return ticket (my understanding is that this ticket is flexible on any trains standard class as long as it doesn't fall within peak period) from london to northampton (depart london on a sun 10+am & return to london on a thurs 4+pm), should i pre-order online or can i get it at a train station?
If i can get it at a train station, do i need to get it from a national rail station (e.g. waterloo, london bridge, euston etc.)?
How do i get my seats reserved (as I'm traveling in a pair and would like to seat together) & do i have to pay extra?
I've managed to get the timetable from national rail website but deliberating whether i should order the off peak train tickets online.
my plan for next week (5th Jul) is to travel from heathrow to waterloo, stay a night at waterloo (with luggage) and get my tickets from the station at waterloo then the next day's morning (6th Jul), tube to euston and take a train northwards to northampton.
just to also check, i can get BUSplus card for 2pounds at the train station when i get my rail tickets too right with a off peak train ticket?
any advise would be greatly appreciated! :)
thanks much in advance and an urgent response would be great!
