What items have you expereinced travelers learned to bring to make things even better(if that is possible!!)? For example, the wife and I throw in a dozen or so of the Crystal Light type drink packets that are made to put in a bottle of water for thos mornings when we're not ready for alcohol and soda doesn't really sound good. We also thow in some salty snacks as the seem to be in short supply in Jamaica. Any other ideas?
