Don't apologise, you're not butting in at all x
And I do agree Shell, Paddington may not be the nicest area, but the reason I'm suggesting to meet up there is that I won't be able to leave work until about 5pm and I'm trying to maximise the time we can all be together. And whilst it's not far from Oxford Street station to Paddington it will still be part of rush hour so Kaz will have to leave it a bit longer to make sure she gets the train, esp if you're not used to the tube system.
But I'm happy to go wherever everyone thinks is best
