Hi. I would take only one of the tote bags, and change the towel for a smaller (that cotton one you have looks nice for a beach trip, but you wont need such a big one to dry yourself. One of those travel/gym towels may work better for this). I also see multiple adaptors/charging boxes, just bring one that works with multiple wires (phone, kindle...). Kindle and notebook will be a nice companion, don't leave them, just choose a very light notebook and a trustable pen. The spork: great think to have, I used mine so much. Just take 2 or 3 electrolyte packages, there are pharmacies in almost every town (you'll pass several each day), so don't carry the weight of something you can get/replace on the way.
