Tasting Order

I am planning a Single Malt Scotch tasting event which will be attended by novices (including myself). I have all regions represented. I'm wondering what would be the most logical order in which to taste them. I was thinking of ending with the Islays since they have the most smoke/peat flavor, but I'd like the opinion of someone more knowlegable than I. In what order would you taste Lowland, Highland, Speyside, Island, Campbeltown, and Islay?
