Argyll and Bute Council have published an updated explainer on the Visitor Levy. The plain English helps explain what the council are thinking of doing, why they think this is a good idea and the process that they will need to follow to implement the changes.
There is a meeting before Christmas at the council to consider a draft scheme which if approved will go out to consultation in the New Year for three months.
