If your ticket was purchased with Armas Trasmediterránea, adding a car requires redoing the booking including the vehicle.
A new booking will be created with all the trip details and the amount will be adjusted taking into account what you have already paid.
Regarding the price, you will only have to pay the difference corresponding to adding the vehicle.
Before confirming the change, you will be informed of the exact amount.
Can I modify the type of vehicle after booking?
Yes, but it cannot be modified directly on your current booking.
To make this change, it is necessary to create a new booking with the correct type of vehicle and adjust the amount based on what you have already paid.
If the new vehicle has a different price, you will only have to pay the corresponding difference.
