as someone who enjoys working on bikes, its because of that that I was thinking that you'll want to get a derailleur hanger alignment tool and have spare bits and bobs, expecting that "stuff will happen", but I'm sure you've already thought of all of these contingencies. It often surprises me how some people can be such hacks with treating bikes, which may be a hassle and frustration for you dealing with Joe Public.
Funny you mention Laphroaig whisky, I spent the month of august in Scotland and biked past a few distilleries, but I'm not a fan of hard liquor, so had no urge to do a whisky tour.
