the ironic thing it the picture the bus company uses to say they are buggy friendly is one of a bugaboo! which CANNOT be folded in one piece you have to take the seat off the frame and fold the frame seperately! most prams with a carseat on the top would take up less space folded than a bugaboo would! and i use a bugaboo and have taken it on the bus loads. no issues in norfolk, if there is space you can use the bus no matter what type of pram/pushchair you have
