I don't mind. When I left Watford Tube Station I turned L, turn L onto Swiss Avenue, turn L onto Gade Avenue, turn R onto Rickmansworth Road towards the roundabout, you will have to cross the road, at the roundabout turn L onto Ascot Road. You will see a Premier Inn, I believe, and you want to go down that road. It is a dead end road. When you come to the end of the road you will see a car dealership to the R and you want to take that R. You will have to cross the road again. When you cross the road you want to go R and you should see a sign for the buisness park. It will be on the L. I know there is a bus that goes to the park if that helps. Google maps was a big help. Hope this helps.
