We are planning to take the bus to Bath from Heathrow and have seen the National Express schedule online.
We can figure most of it out, but are a bit worried about what would happen if our flight is majorly delayed. I know we can rebook a new bus time, but how hard would it be to get a seat on the next bus (like, if the next bus is full, could we end up waiting for hours and hours)?
Also, how far in advance do we have to make the reservations?
Thanks for any help you can provide.
