Right, bang the following postcode in your sat' nav's: KT21 1BE - Grove Road. You'll see a pay and display car park, next to Oakhill Garage (you can't miss either). Park in there (it should be free by then). It's as safe as houses, so no need to be worried.
Look at the following link, and you'll see the pub we'll be in (The Leg of Mutton and Cauliflower), on the junction of the A24, and Rectory Lane. The restaurant is also on there (The Curry House), further up the A24, just before the cross roads at The Marld, and Park Lane.

You can view it all on Street View as well, if you want to get the full low-down. You can also see my dad pulling out of Grove Road, in his black Freelander
As for what time people are turning up, you had better ask everyone. Mart said that him and Steve should be up quite early, but I don't know what time.....
