Think about packing these items next time you get ready to travel somewhere:
Mesh laundry bags: They come in handy in your suitcase for keeping smaller items, like socks all together. Plus it's easy to see what's in them. You don't need to spend a fortune on them, either. Go to a dollar store where they often come in packs of three sizes.
Calculators: While you're at the dollar store, pick up a couple of cheap calculators. Use them to figure everything from your tips to the exchange rate.
Plastic table cloth: These inexpensive items are great with kids. Use them on the beach when you're having lunch and really don't want sand in your food. Or cover a not-so-clean picnic table or use one on a bedspread to keep it clean.
Glow in the dark key chains: Again, these work for kids as well as adults. They give off just enough light to find your way to the bathroom.
