We were a group (family) of three and came early - but although we were first in line - they didn't direct us to the right bus, so we didn't get to sit together

Not good, the coach driver had to keep stopping because people using the toilet kept pressing the SOS button instead of the flush.

Megabus Cardiff London recent customer reviews
I booked 6:30am bus and had to reschedule my booking to 2:30am. I had to pay extra £9.47. I came out to the pick up area around 2am just to be early enough. The bus was delayed for 1hour there by arriving around 3:45am under this cold weather. My question is, i paid to take my time back, who will now pay me for extending my time for upto 1 hour plus under the harsh cold weather.
