Making reservations for every night?

It depends on where you are, when you're there, and how picky you are about your campsites. Around here reservations are a decent idea on the weekends but less necessary during the week. I gather things tend to be a little more open in tbe west...and a lot less so in places like Florida during peak tourist season.

There are differences in temperment also. Some people are planners by nature, and some wingers.
