Q: I have read that "T-Casual" travel ticket is valid during a calendar year but can it be shared with other members of the group? May the Barcelona Card also be shared with other members of the group?
A: The T-Casual travel pass and the Barcelona Card are completely separate products and should not be confused.
The Barcelona Card only allows a single person travel and discounts and may not be shared amongst other members of your group. The T-Casual has only 10 journeys issued on it. When the 10 journeys are used up the T-Casual card expires.
The T-Casual cannot be shared with other persons on the same journey at the same time. However you can give the T-Casual card to someone else to use when you are not using it.
The Barcelona Card allows unlimited travel and therefore it cannot be shared with other members of your group. I also would like to clarify one other point. The T-Casual is valid within a particular calendar year and will expire at the end of January each year.
The Barcelona Card also offers many other benefits other than a travel pass. It also offers discounts and free entry to many tourist attractions and gives discounts on other Barcelona related services. The T-Casual is only a travel pass.
If you want a travel card that gives you unlimited travel within your stay you can consider the Barcelona Transport Card. This is valid for a specified number of consecutive days and gives you unlimited transport on the Metro, Buses, Trains and Tram in Barcelona city centre Zone 1. The Barcelona Travel Card does not cover you for any discounts to Barcelona attractions however it is cheaper than the Barcelona Card.
