There is a upper / lower tier split entrances so you won't be able to meet up at half time. There is a fan zone outside pre match. I didn't go but I'm pretty sure I saw away fans within it.
Was going to post that'll be the 1st away I'll miss - fingers crossed for Marseille and all that - before deciding to go anyway with my son. f*** it. We will only be this good for so long and are due to beat city.
