you can pay at the doors when they open at 9 am to get in no problems there
as for getting there it depends whether you want to get involved the scrum for cheap timber parts.
if you do that you realy could do with with arriving around 7.30 to 8 am ish, get a cup of tea out of your flask, get your self together and jion the que at the reasonable front of the doors,
if you dont want timber pieces then turn up about ten ish to miss the madness and then enjoy your self
i will be there as a steward for about 8am and there is normaly one or two queing all ready.
the last point is that the sprint for frames is only in the thornes shop area only and the international hall and the rest of the sellers hall and the consevation hall are normaly very very civilised
