Take the best camera you've got. A trip like this is the point of having it. Also, starting right this minute, carry that camera everywhere, to the grocery store, to the mail box everywhere you go and everything you do. Get used to the feeling of having it with you all the time. This will make it much less likely to be left somewhere. Although I pretty much always have a camera close, I make a real point of it being a part of me starting about a month before I go on vacation.
