The campground in Longyearbyen is right outside the airport. I walked down the hill and set my tent up. It was warm and sunny and at nearly 80 degrees north, the sun never even got close to the horizon. The first night I was there I slept very badly in the blazing daylight, worried too about the minuscule risk of polar bears. It only took a couple of days to get used to sleeping in broad daylight, and my tent was not at the edge of the camping area so I thought any rational bear would not attack me first, so I slept fine after that.
