I will be in the UK for a week, staying with a friend who lives 40 min from London off the M4, I believe. She will be working three days out of the seven, so I will be on my own. Can anyone recommend transport from Slough to London? Should I rent a car or is there a possibility to take the rail system? I'm a little nervous about driving to London, through am used to driving in NYC traffic - but from what my family says, London is a whole different ball of wax (especially with opposite side of the road driving)
Any recommendations? Thanks for the help in advance!
