Yes, that's the one. It's been changed around a bit in recent years, though. You follow the signs from Victoria rail station, anyway, and then look for the bit that says 'arrivals', and there ought to be a sign up (possibly...) to say where specific coaches are coming in. Otherwise, I think there's a waiting area there. Last time I met my Mum and sister & family there, they got there early and were sitting having coffee on the pavement tables outside a cafe...
