One thing you don"t have to pack is a swimsuit. The lounge chairs at Club Orient aren't the most comfortable, so we take chair pads. We also take (believe it or not <img src="http://www.traveltalkonline.com/forums/images/graemlins/Grin.gif" alt="" />) a small folding table for our drinks - keeps sand out of them. And also some of those laundry "bubbles" for the machines. You mentioned casual clothes for when you leave the resort - nice but not formal would work.

I'm going where the weather suits my clothes.
