You can't change a passenger's name. What you would have to do is cancel the original reservation and purchase a new one at the current bucket (fare). But if you want to take a chance that you will not be asked for ID (which seldom happens on the NEC), why not just leave it as it is! :huh:
Okay so here is another thing. I am booked on train 86 on the fourth of July which doesn't run on the fourth of July. So I guess it is time to give them a call and get that fixed. Must of slipped through the cracks.
