It was 40-odd fo the bus when I looked at it last year. Rayanair was a funny schedule no? Or have they improved the service? Last time, I could have got there & back in two days, or had to stay the best part of a week if I wanted only a day longer. The combined train/ferry ticket was only slightly dearer (55 OTOH) & proably more worthwile for time & comfort. The train companies do combined rates from all over the UK, so do not try to book it through the normal rail portal as you will get a stupid rate, plus ferry. Website was a fucker to find - I'll away & look again.
