When visiting Barcelona you need to decide which travel ticket option best suits your needs for getting around the city. There are several options to choose from but lets just look at the T-10 and the Hola BCN!
The Hola BCN! ticket is available for either 2, 3, 4, or 5 days and can be used by only one person. These are full 24 hour days so if you buy a 2 day ticket and you make your first journey at 10:00pm in the evening, say after arriving on your flight to the airport, your ticket will not expire at midnight on the next day but at 9:59pm two days later. This ticket is valid on all Metro lines, buses, trams, local RENFE trains and the funicular railways in the Zone 1. It is also valid for your journey from and to the airport. This ticket costs about €7 a day depending on how many days you choose.
The Metro, or underground, in Barcelona is an excellent and inexpensive way to get around the city. You can also use it to get from the airport to central Barcelona too. TMB that run most of the metro lines, except for three short ones, state that 90% of stations are wheelchair accessible so far with work planned ongoing to others.

I would suggest printing out a copy of the map to carry with you when travelling, I did and found it invaluable for planning my routes, especially when working out how to get to places if the obvious route included a change of lines that are inaccessible.
I am J David Garnett, I was born with spina bifida, in north Wales, during the 1960s and have always lived there. I have been a wheelchair user for over 50 years and enjoy travelling.
My first overseas trip was to Lourdes at Easter in 1977, in the following two years I went on school exchange trips to Bayeux in France and then Leeuwarden in the Netherlands, or Holland as we called it. It was then a few more years before I travelled overseas again to Esbjerg in Denmark (1985), Katowice in Poland (1986), Eindhoven in the Netherlands (1987) and West Berlin in West Germany (1987). These were all group trips.
In 1990 I decided to take my first solo overseas trip and chose Sunny Beach (Слънчев бряг) in Bulgaria where I spent three weeks at this seaside resort. I returned there each summer from 1991 to 1995 for holidays ranging from two weeks to six weeks. In 1993 I also spent Christmas week in Disneyland Paris.
