Sorry, Aero, didn't see yesterday's message.
If you're coming from Chatham, then head towards the town centre. When you come to the big roundabout which goes across 2 bridges, take the directions for Tonbridge. You will go up a hill and then the road forks - one fork for London and the other for Tonbridge. Stay in the left hand lane and head for Tonbridge. The Osteopathy school is on the right hand side just before a church. There is another church on the left-hand side and if you go past this, you've gone too far.
Unfortunately, I have friends coming on Thursday and I'm going to be out on Friday. Could manage Wednesday.
