We have to make a road journey tomorrow from Essex to Chichester. We’ve realised tomorrow is set to be the busiest day of the summer for travel to Gatwick and would like to avoid - as much as possible - getting caught up in the jams. We can go pretty much any time of day , but have to go some time tomorrow. Does anyone have any idea when the busiest/quietest times are likely to be, or will it just be a nightmare all day?
