As a large group of individuals in what will be considered as a car club by most maybe it could be done separately over a two/ three even four year tour. That way have a meeting venue for daily outings. Split that coastline into four and each one could be done from same hotel / B&B in that area spread over three/four days each year. Thinking each car could book into any hotel within a reasonable distance of meet up venue. Not much difference to going touring in your Z to Scotland / EU, after all the Scottish run has been going for a few yrs already. Might be easier on Paul just to get us together for dailies rather than for 7/10 days. That way it would be open to more individual cars if leave/ hols is a problem. Just think if it’s as good as I imagine you could be going back each year, if not nothing ventured nothing gained as they say. Just a thought!!!!
