National Express Reading Carmarthen recent customer reviews
Bus drivers friendly and informative. First part of the journey was driven by a driver that kept the bus too warm. Not good when wearing face masks. Second driver on the second half of the journey kept the air flowing nicely with good ventilation which kept the bus cooler and more comfortable.

Good service, eventhough the bus arrived late to Reading we made back time and was a good journey.

I was a bit disappointed as the coach stopped for a 45 minute break without informing us first, which meant my husband had to wait 30 mins, I know it’s not that long but feel he should have told us so I could have let him know 😩
