It's your safety net, your "in case of emergency" card.
But your credit card may end up at the center of your vacation crisis if you don't follow the advice of Ben Woolsey, director of marketing and consumer research for CreditCards.com.
These are Woolsey's five worst credit card goofs while on vacation -- and what to do to avoid them:
GOOF #1 - YOU DIDN'T NOTIFY YOUR CREDIT CARD COMPANY ABOUT YOUR TRAVEL PLANS. "Unless you call your bank in advance, your card could be shut down or flagged for fraud and rendered unusable," said Woolsey.
Solution: Call your card's customer service line and let a representative know you may use your credit card while on vacation and to mark your account for anticipated charges at or near that destination.
