Meet at Solstice and then head through the countryside.. We'll be posting alternative routes on the site in due course... if you mark Solstice as your last meet up point and then you can use alternative routes from there. Shouldn't have to leave as super early then.
Also we moved it away from being the busiest weekend of the year for the A303
I think your estimation of 45 minutes from solstice to haynes may be a little on the short side! its usually queing from solstice on a friday from 2.30, i drive it most days! sorry to be the bearer of poo news! there is a scenic detour out the back of amesbury that joins the 303 further down (i guess this is what HotWire is on about) its a few miles longer but you don't hit traffic, which means you don't overheat :-)
What is the route then guys? I also think avoiding the A303 at the Solstice roundabout is a must. I am used to doing London to Salisbury so know how bad it can get. Best to turn off the A303 at the new Solstice park, before the roundabout. I wouldn't really know which way is best to go from there though. I am going to suggest - A303 - off at Amesbury before main roundabout Go South on A345 towards Salisbury Turn right onto B road at Dumford, through a couple of hamlets and pick up the A36. A36 back onto A303. Would that work?
I'm heading down on Friday too,.. I'm not sure what time (as I need to swing by the Dungeon and get some bits) but I suspect it'll be before you,.. however I may pop into the services to check for people just in case
