Just like my wife. We have a big bottle of Lagavulin, purchased at Costco, just for her. It sounds like you may want to spend some time on the isle of Islay.
But if you also want to spend some time around Speyside, that would be a different part of the trip, as it's quite a ways away. Glenfiddich is in Dufftown. But I also recommend the town of Tomintoul, just to visit the
Whiskey Castle. It's definitely a tourist trap, with 1/2 the business consisting of a store with hokey souvenirs. But the other half is a whiskey store with 500 varieties of single malts. And the proprietor really knows his whiskeys! I spent a pleasant couple of hours there sampling and comparing his wares. And then I had to wander the town for a couple of hours until I was in shape to drive again
