Just be aware that the security guards at Boris' house will ask what is going on when you all meet. If they don't like the crowd they will call the police.
From what I remember of the last time, they weren't so much worried by the crowd, more the fact that we were blocking the embankment and people couldn't get past, as long as we keep a nice unoccupied area, we should be fine.
