Its no where near that size, majority indoors quite a cool vibe to it, missed last years, the usual vendors are there so you'll be able to get most of the parts at a slight knockdown, two years ago I did note that some of the foreign and the home grown parters were chargeing silly money for some parts but then some other items were peanuts so ballanced itself out I suppose the mezz level tends to sell the nic nacs toys and mags etc with the ground level being the big vendors.....
the queue in can be a pain especially in the cold but atleast the cafe opens early
