Couple of things I've found useful as well. You know those plastic travel q-tip containers? Well they work perfect for holding enuff cigs for the night and tucking inside my bra and they don't get wet from sweat. I don't like to carry a purse so it works perfectly.

Colored washcloths for sweat rags so they don't get mixed up in the hotel linen.

Ziplock baggies for just about everything.

I also bring the 1's for tipping. Much easier then trying to find small Jamaican bills.

Laminated conversion cheat sheet.

Oh and last year I found a cheap shower thingy that hangs on the shower rod that has like 6 pockets. That was super nice.

Anti chaffing powder for those of us who have thighs that rub together (men can use it in a certain area too ) I have some called Monkey Butt and it worked great this year!!

I'm sure there are more but can't think right now.
