In travelling, careful planning is better than packing everything in sight which results in more suitcase than you can carry. But this doesn't mean that the traveler should under pack. For instance,you won't enjoy the tropical paradise if you fail to pack enough bathing suits, beach clothes, and so called "resort wear" Never forget the there are plenty of resorts where you won't feel comfortable in the evening without a reasonably elegant suit or a pretty dress, and that part of the fun of travelling is dressing up and looking you best.
