Quote from WraithGaming:
It's a real shame that this is in Portsmouth for me. After doing a bit of research a ticket to Portsmouth from Durham is around the same cost as a flight to Sweden. I'd love to attend but the money isn't ideal, especially as I am an unemployed college student :D. Anyway I look forward to see where this goes.
Have you looked at National Express coaches rather than trains? They take longer, but the prices tend to a whole lot cheaper (especially if you book them in advance). I don't know what sort of prices you are getting on trains, but you can get return tickets between Durham and Portsmouth for less than £50 at certain times of year. But yeah... really depends if you are willing to sit on coaches for 10 hours.
