Know Before You Go
It is a short drive from Heathrow but traffic on the M4 is always a nightmare. Be careful of the speed cameras as you drive through Slough and Farnham Royal. While living in the UK, I was caught on camera on my way to Stoke Park on Farnham Road in Slough. The fine for my ticket was based on my previous years income. My penalty for doing 34 in a 30 mph zone was Gbp 347.00 ( equivalent to $545.00!). Ouch.
