Some local opinions please, to anyone who has done the journey recently. We are holidaying in Watchet end July, and I'm weighing up up whether to go M4-M5-A39 or M3-A303-A358.
My head (and AA routeplanner) says the first option is probably the quickest, but I do find the M4 a rather tedious schlep. We'll be coming down on a Friday afternoon, just as schools break up, so I'm expecting fairly hideous traffic either way. Any real showstoppers for option 2? Been a few years since I did the journey.
