Hello D70ar9
A group must travel together.
The group leader will receive 1 ticket valid for all group members. A group cannot have less than 10 group members in order to benefit from the group discount. If you want to split the groups, it must have at least 10 members and for each you need a group leader.
In addition to the ticket, a compartment on the train(s) will be reserved on your behalf.
If you want your group members to travel individually, you cannot benefit from a group discount and must purchase regular tickets (no Supersaver tickets).
Kind regards,
Roland
