National Express Cardiff Swansea recent customer reviews

After arriving early at the bus station, we were given wrong information by a member of staff, which left us waiting 3 hours altogether before we got the right bus. Travelled from Spain. No facilities at the bus station. Late for our family reunion, and very disappointed. Day ruined, due to staff incompetency.

The bus was an hour late and the air conditioning was broken on a very hot day.
