I have only ever used the service once and that was when I was getting on it from Brough to Hull.

I just used my day rider with it being stagecoach and had no problems. Not sure if this works with it being all the way to cas but technically it should. A dayrider is £2.80 and allows you travel on any stagecoach bus that day. Might be worth checking before you try this though.

I've used it to go to Leeds, it was £9.50 day return. about 1hr 30 to Cas.

Quick way to find out is to phone bus calls on 222222

Thanks for the replies, gave them a bell and its £11.

is this for rugby?

if so you may want to look at the train. i went from hull to wakefield for £11 return
