PLEASE, boat from ireland to england and train discounts needed!

gron1979

Really hope someone can help me. I live in ireland and have just booked a weekend away for the children this weekend to north wales. They have never been on a boat or a train and are so excited. I had intended to use the free ferry voucher as we really couldn't afford to take the car over. However when i rang up to book it a couple of days ago there were no spaces on any boats for the day we were going over and coming back. So it is now working out at just over £200 for the four of us, which is really more than i can afford. If anyone knows of any discount codes i would be really greatful, thanks
