Through the years I’ve seen posts from people wanting to haul along rice cookers, waffle makers, toasters, etc.! I assume they are driving behemoth SUVs rather than flying and thus can pack everything but the kitchen sink.
For me travel is supposed to be different from home, so if I find myself without coffee in my room/cabin that means I get a pleasant walk in the morning in search of my a.m. caffeine fix. One of my favorite travel memories was years ago, first morning in Venice, totally jet lagged, wandering along the narrow ways finding a seat outside on a canal and tasting my first Italian espresso while watching Venice slowly come to life.
