M25 junction 10 and A3 Wisley interchange ?

[RichB]

I'm heading to the RAC Club at Woodcote Park, near Epsom tomorrow morning and I need to be there between 9:00 and 9:30. I'll be travelling in from Farnborough/Frimley area so I could head in on the Hog's Back or I could cut across country but either way I wonder what the A3/M25 interchange is like in the mornings these days, heading east towards London?
