Looking for one less thing to pack? How about seven? Simplify your suitcase by purchasing certain items at your destination instead of schlepping them on the odyssey from home to hotel. Most major airlines charge hefty fees for checked luggage, as well as oversized and overweight bags. So it makes budgetary sense to lighten one's load by buying a few things in the airport terminal or upon arrival, after suitcases have already been weighed and measured. Some things weigh more than others, but the more you leave out of your bag overall, the lighter your luggage will get.
It all depends on where you're going, of course. If you're heading to a rainforest lodge in Borneo, this advice is essentially irrelevant. (Convenience stores are not so easy to find in tropical jungles.) But travelers visiting big cities, resorts, beach towns, and even national parks will likely uncover plenty of places to purchase the following items for reasonable prices.
