Can the public transport cards (bonobus or Multiviaje), be used by more than 1 person? (simialr to how it is in Granada) Or is each card restricted to a single person?
On the Tussam website https://www.tussam.es/es/condiciones-de-las-tarjetas
(i) there is a schedule of tickets which are personal, Tarjetas Nominativos, to be used by only one person. The Tarjeta multiviaje is not on the list nor is the Tarjeta turística de 1 o 3 días;
(ii) there is also a schedule of tickets which are not, Tarjetas al Portador. The Tarjeta multiviaje is on the list, but note that one can only use it up to thirty times in quick succession, so a larger group is recommended to use two cards.
