My trip to Cardiff was very pleasant, and I wanted to return early. I was pleasantly surprised, and please that the process was no hassle, no fuss, and the gentleman there at the ticket agency was very helpful and made that happen for me!!!

I along with one of my friend showed the ticket to the bus driver but the bus was wrong bus but he didnt say anything . We were going to cardiff but we was placed in a return bus to London. I missed my class and had to buy a new ticket to Cardiff. And I was in a hurry to catch the next days class so I didnt complain to anyone. I am a new student here but It was completely the drivers fault. If he checked the ticket clearly it would never happen.

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.
