Going to watch the MGP this weekend - first time I've been to either the racing or Donginton, So... Do the font have any recommendations on places to sit (grass is fine) and the best entrances for them? I'm going in the car (I know I know) so that is a factor. I know the gates open at 6am, but what's a realistic sort of time to try and arrive to still get parking and potentially a reasonable seat on the grass?
