And, to add to what I've already posted. Make sure you have a good camera with plenty of memory for photos. I am a prolific taker of photos, so in addition to having my laptop to download to every day, I also had a camera attachment that would let me use AA rechargeable batteries, along with the two standard rechargeable batteries. Even then, I got caught once without well charged batteries and still had to buy some regular AA batteries to get me through the day.
