An ordinary travel mug isn't just good for your tea and coffee. It's also a great place to hide valuables in your hotel room since it's fairly inconspicuous, and an unlikely target for thieves. Here are a few more travel hacks that will make your trip easier and save you a few dollars, too.
First and foremost, scan or photograph your passport and ID. Then email the images to yourself. This way, you'll always have a digital copy handy in case of loss or theft.
Next, if your clothes always seem to be taking up too much luggage space, try rolling them up instead of folding them. This will open up a lot of room, which can sometimes save you from paying extra baggage fees.
Packing an empty water bottle will also help you squeeze a few more dollars out of your budget. Just fill it up once you get through security, and you won't have to buy overpriced airport water ever again. You can also re-use the bottle throughout your trip to save even more money.
Lastly, if you happen to forget the wall plug-in for your phone charger, check the back of your hotel TV. A lot of the newer models will have a USB port where you can recharge your phone without spending more for a new charger.
Give these travel hacks a try on your next trip. Not only will you lower your expenses, but you'll avoid a few headaches, too.
