There are often plenty of free tickets knocking around; I've never paid to get to the NEC one.
The last time I went was 2009, for the CoLAB competition. There wasn't much that interested me (even for the short time not on the stand), so I don't think I'd pay for a ticket, or the train fare to the NEC, or even to London. Some of the talks might be worth catching (I wanted to see Paddy Dillon's lightweight backpacking talk, if only to see him wave a SqueezeBox stove at the punters...).
