- There are huge discounts on purchasing 4 seats
From @glebm
I'm thinking that we could take the money upfront when you join a departure (datetime, from station, to station) The hold gets charged to a group of 4 when the group 4 if full, and the user receives a confirmation email (i18n en, es, etc. would be great) If the group is not full at N hours before departure, the money is returned, and the user is notified
We would need to get data from renfe (no api) for schedule and ticket availability
