*Map
*City guidebook (a small one) or copied pages from a guidebook.  When I am done with the copied pages, I throw them away.  There is no need to bring them home.  I do bring my map home with me if I don't have a second one at home.  It's good to keep one for future reference. 
*Journal/pen/small spiral notebook, which contains various information
*Travel language book
*Packet of kleenex
*Small water bottle that I purchase and later fill at the hotel
*My super light tote umbrella (unless I know the weather report for the day)
*Camera, 2-3 rolls of film per day
*2 sets plastic utensils for picnics or snacks along the way (depending on where I'm going that day)
*Wet naps
*Contact lens eye solution
*Copy of our passports
*Lipstick or chapstick.
