Right, I spoke to my Dad the other day about train tickets. Basically, if anyone is there for 3 days or more, you can buy a ticket (from june onwards) that allows you to get the train anywhere for three separate days out of 7. They are unsure of the cost, but i think whatever Jager paid before, it won't be much more than that.
Sorry my brain is a bit fried atm, so if it doesn't make sense i apologise.
