Edinburgh to LAKE DISTRICT – return train 6th-8th July ?

I booked tickets ages ago to spend a weekend in the Lake District on 6/7/8 July but now I can’t go. Outward Journey is Friday 6th July 2012 Departing Edinburgh Waverley at 6.12pm (Arrive into Oxenholme Lake District at 8.12pm) (Depart Oxenholme Lake District at 8.27pm) Arriving into Windermere 8.46pm Return Journey is Sunday 8th July 2012 Departing Windermere 7.06pm and (Arrive into Oxenholme Lake District at 7.23pm) (Depart Oxenholme Lake District at 7.30pm) Arriving back into Edinburgh 9.39pm I booked these tickets really early so they were only 9 each way at the time. So I’m asking for 18 in total for these July return tickets to the Lakes. A ticket bought on the day would cost 110 return so this is quite a bargain :o)
