Obviously I'll keep checking what is going on, and may re-evaluate my decision. It's probably going to be easiest to get a train (can't be A.R.S.E.'d :-) to drive, have enough of that throughout the week). If I get there after mid-day then it will take 2hr46, before then it is close to three and a half hours.... looks like it will cost a minimum of £25, and that's if I know which train I want to catch back. Not bad I guess.
I might be there, I might not.
