If you want a much more relaxing journey after you come back into God’s country I would suggest you come off at Gretna, through Gretna Green and take the
B7076 all the way up past Kirkpatrick Fleming, Lockerbie & Johnstonebridge till you hit the A701 Dumfries to Moffat. A mile or so on that & again back on to the B7076 to Abington.
At the motorway JCN take the
B7078 towards Douglas Water.
On that road is the Redmoss Hotel & truckstop
About | Red Moss Hotel
You are only about 45 mins from Hamilton services.
Maybe worthwhile having an earlier stop and and set off earlier in the morning.
This trip is always within sight of the motorway but is virtually empty so you dont add much time to your journey but saves a lot of stress !
