Today, my daughter booked some rail tickets on line, then went to her local station to collect them from the station machine.
Result:
West Malling to Warminster and back = 2 tickets + 5 blank (?) seat resevations
Warminster to Ryde (IoW) and back (2 persons/3 split tickets) = 12 tickets + 12 blank (?) seat reservations
...............and of course a collection receipt !
32 bits of paper !! Good job she didn't have to pay for all that paper - that would have negated the split ticketing savings.
PS: She still has to email Hovertravel to book seats on the hovercraft....
