To come up for this or not... that is the question.
Linda and I are also giving this question serious consideration.
Trains are around £40 return, not looked into any other travel options yet.
Accommodation: hotels range (obviously) and I've stayed in quite a few in Sheffield - but would chose one closest to the venue for ease of getting home afterward - so probably the Best Western (Cutlers) which is not all that great, but very central... a twin room without breakfast is around £37.50 per person. (ie. £75.00 for the room, split by two people...)
Anyone else from London considering going?
