What's your favorite "unfun" part of travel?

I'm absolutely obsessive when it comes to plotting things on maps. Sights, restaurants, bars, etc. I end up with a map that looks like a serial killers life's work every time I go somewhere.

I just like thinking about the trip before I go. Then I like being able to just open my map and see what's nearby when I'm there. I don't even make an itinerary, I just like the objective based wandering.

Wondering what other things people enjoy about travel that most people don't.
