Two things I thought of that I didn't see, a first aid kit and one eyeglass repair kit, (even if only for your sunglasses). Everyone talks about moleskin, water bottles (we bought brita filtered water bottles), and I found this sanispray at walmart to spray on toilet seats. There are lots on travel items in the trial size aisle of any chain store like small TP rolls, (you never know), antibacterial lotion and wipes, ect. Ponchos and umbrellas, cameras, film and batteries. I even read somewhere that they pack a travel size microwave, I guess it just depends on what you need. I've been picking things up along the way that you find and think will be helpful. A medicine bag filled with pain relievers, allergy medicine, bug bite and sun relief sprays, and tummy pills. Good sunscreen and a chapstick with sunscreen. A good bug repellant. ect. Good Luck!
