One of my favorite pass times while traveling is to get lost in the city. In Paris, the city that never sleeps, everyone else seemed to enjoy the same pass time. There were so many people walking around, dinning in cafes, playing games in the parks, drinking beer by the river. It was wonderful.
I have to admit, I was a little thrown off when it was 9:30pm and the sun was barely beginning to set. And was up as early as 5am. It was hard to adjust to the time difference so I spent a lot of time looking out my hotel window, watching the sun rise and the late night strollers head home.
