If you can - pop over to Islay - great distilleries!! - recommend the Laphraoigh one.
Went to Mull a couple of years ago - roads in the area are very potholed so take it easy & enjoy the view.
Never mind the midges - I very nearly got a golden eagle attached to the windscreen at one point - now that would have taken some cleaning off - so don`t forget windscreen wipes(for dead midges etc.)
Enjoy - I am very envious.
By the way - if on Mull - get some Mull cheese (can be got direct from farm just North of Tobermory
