National Express London Cardiff recent customer reviews

the only reason i’m giving the power one a bad ranking is because someone prior left the plug in inside the charger— i couldn’t pull it out therefore couldn’t charge. i later switched seats when people left and it was fine from then on. the wifi was spotty at best, but i wasn’t expecting too much from bus wifi. besides those two— great experience

Every thing was fine till we reached the Cardiff railway station stop. There was a scheduled driver switch, but the reliever was not there. We had to stay put at this point for 20 minutes till the next driver came. Finally reached our Cardiff destination 30 minutes late.
