For substantial trips I use a manilla folder, with a summarized itinerary, include maps and directions. Things like lodging and activities stapled on the left side, and travel stuff on the right. I like having a hard copy available of everything, "just in case". Many years ago I got such packets when I did corporate travel and it was invaluable, so I adopted it.
When my son and two buddies did a cross country roadtrip after they graduated from high school. I made packets with all the info for each of the boys, and a set for each set of parents, so they could follow along. The parents were blown away.
