I also make sure to have a bathing suit, cover-up (doubles as a dress), and flip-flops in my carry on.
My other tip:
I still like American Express traveller's cheques and find changing them at a cambio to be easy and quick when there isn't a long line. I just like the peace of mind that comes with knowing they can be replaced if lost or stolen. Not sure if Amex would be able to get new ones to me in JA very quickly, but I take an ATM card and credit card as backup and keep those separate from the cheques. My bank still offers the cheques free with my checking account, although the last couple of times I've purchased them, the teller had to get some help from a manager because they hardly ever sell them anymore.
