Notify your credit card company when you are going on vacation. Charges from strange areas may make them think your card was stolen and reject a charge you may want to make. We were going to Cancun, Mexico.
When I did that, the Visa representative mentioned that I should be very careful and keep the credit card in sight at all times. Don't let them walk away with it and return with a slip for you to sign. Something to keep in mind!
