HB, might be best to reduce possible pressures, starting out with avoiding ferry trips to some Scottish island, even in the "sheltered" waters of the Clyde estuary the ferry can be cancelled due to rough weather, even in Summer.
I expect the increased number of folk using them as the result of social media postings, and who may be running to any sort of schedule might be somewhat disappointed to find their plans disrupted by cancellations..? To turn up without a booking might not be wise on any busy route..?
If you stick to the mainland there are perhaps some country roads not encumbered with baby boomers in their campervans and caravans....(-:
A friend runs a guest house near the borders, Gordon the proprietor was a Rally Navigator and knows plenty of quiet roads around the borders and well beyond, his guest house has been on TV (four in a bed) Trip advisor has some data on it and a Morgan crew have sampled staying there too.... Tim H may be able to provide you with a heads up...?
Whatever you are planning I hope it works out as you might wish..
