If you’re traveling this summer, don’t let scammers ruin your vacation, reports the AARP’s Fraud Watch Network.

Thieves prey on unsuspecting travelers through front-desk fraud. Hotel guests receive a phone call in the middle of the night, supposedly from the front desk. There’s a problem with your payment, the caller says, asking you to confirm your credit card number. Only it’s not the hotel staff calling (they’d wait until morning); it’s a scammer using a lobby phone.

Never give your account numbers in unsolicited calls; contact the front desk yourself.

Contact local law enforcement or the AARP Fraud Watch Network www.aarp.org/fraudwatchnetwork, or 1-877-903-3360 to report a scam or for more information.
