Although it's rare that I actually need whats inside, those little hotel shampoo bottles can come in handy for later travels. Since TSA requires that your liquids be under 3oz, these little guys are a perfect fit. Just empty out the stock hotel shampoo, and load them up with your own, or full them with lotion, perfume, sunblock, hair gel, whatever you need while on the road. Plus, you won't have to buy any travel sized bottles before your trip, so it's a great way to save a few bucks.
