I like the idea of travelling -- seeing new places, new scenery/nature, eating new foods.
I hate the logistics of travelling -- trying to catch your flight/train/bus,having your flight delayed, pushing and shoving through crowds at the airport, being herded like sheep on group tours, trying to communicate with people who don't speak the same language, getting lost, waiting in airport lounges, eating crappy food while waiting in airport lounges, losing luggage, dragging heavy suitcases or backpacks around, jet lag...it's all just so exhausting and stressful.
I really have to weigh whether a location is worth the extreme hassle. Right now, only Australia and New Zealand make the cut for me.
