Travel Money Mistakes to Avoid

When budgeting for a trip, we often list the big-ticket items -- airfare, hotel, lodging, car rental, attraction tickets -- add them altogether and call it the final price. But the trickle of funds to other costs starts almost as soon as we start moving: gas to and from the airport, tolls, airport parking, overpriced bottles of water in the airport and more.

That trickle doesn't stop when you arrive at your destination; think cell phone charges, bank fees, hotel Wi-Fi and housekeeping tips, to name a few. To avoid spending more than you have to, check out these 10 money mistakes to avoid while traveling.

1. Don't forget to let your bank know you will be traveling.

Forgetting to call your bank before traveling abroad is a common error that even frequent international travelers make; it slips your mind until the plane touches down, and by then it's often too late. These days banks have almost zero lag time in noticing a debit or credit card being used abroad, so you will get shut down on pretty much your first swipe in a foreign country.

As banks have gotten more sophisticated about tracking card use locations, this can be important even important for domestic travel, and most banks recommend that you let them know about those closer-to-home trips as well. Fraud detectors can be tripped if you're suddenly using your card across the country, making more or different purchases than you usually do or charging unexpectedly large amounts (such as a weeklong hotel stay).

Note that this applies to debit cards as well as credit cards, and you sometimes need to talk to more than one department even inside the same bank to get them all approved for travel.

2. Don't overlook bank and ATM fees.

While traveling internationally, each time you go get cash you will likely incur a fee of some kind. These can vary a lot depending on whether the ATM is run by a large bank or not, if the bank is on your card's network and more. Keep in mind that fees can change from year to year, so it's worth checking before every trip.

3. Don't fail to make a plan for getting to your hotel from the airport.

That first taxi ride from the airport may be your most financially vulnerable moment of any trip -- the time when you have no idea how far it is, what a fair price is for the ride, whether you have lower-cost alternatives such as a train or bus, or even whether your hotel has a free shuttle. It is best to figure all of this out before your trip; when you arrive you are tired, often without much cash and carrying a ton of luggage. You don't want to be fumbling around trying to figure all this out on the airport curb.

4. Don't underestimate your cell phone bill.

How much could a few texts, a bit of mapping, a few email checks and a batch of social media updates cost per day? Plenty, it turns out. Even if you purchase an international roaming plan, these often have pretty aggressive data caps, and your data allowances can disappear quickly.

5. Don't forget to research the local exchange rate.

Especially in the first several hours at your destination, having done a little research on the local exchange rate against your home currency can make a huge difference. Often it takes a couple of days really to have a handle on how much things cost, but this can take even longer if you are traveling in an area where prices may not be so fixed as they are at home. Knowing the exchange rate cold so you can do the math quickly in your head will help considerably.

6. Don't bring traveler's checks.

Barely anyone accepts them anymore, they're not cheap, you have to invest a fair amount of time in obtaining and purchasing them, and credit cards give you a far better rate of exchange in most parts of the world. Skip 'em.
