I like to plan some aspects of my trip, but leave most open to "What do I feel like doing today?" or "Oh, you (random stranger) recommend this amazing hike I didn't know about? I'll try it tomorrow!" The idea of negotiating what time we leave, where we go, do we stay longer or head back, are you ready yet, are you hungry? with another human being in a place like this, with SO much to do, is exhausting. The theme of my life: I want to do what I want to do, when I want to do it. The end.
