so a lass i know from the usa is going to westminster university next month, ive agreed to go and see her up a couple of days after she gets here and have just realised how far into london it is

i cant expect her to tube it anywhere so soon after getting here so got no real choice but to drive in. i realise ill have to pay the congestion charge which is no big deal, but just how much of a cunt is it going to be to actually get there? ill be coming from the west down the m4, unless theres a simplier way of approaching?
got my mate garmin to help me out but even she gets lost sometimes so im a bit worried
