Help! I have a medical condition which means at times I need the loo more often than most people. I am going to have to travel from South Mimms round to Guildford. Sometimes it will be fine, other times I may be desperate especially if having been stuck in traffic.
I know there are no service stations as such but is there any junction where I can drive off the M25 and will find a garage or supermarket with loos within a mile or so of the junction?
