Greece is best experienced when the crowds thin out, either in the gentle heat of early spring or the cooling days of late autumn. You get the white-washed villages and blue waters without fighting through thousands of cruise ship passengers for a dinner table.
A trip like this usually runs about $4500. To manage that cost, we look at using the Citi Simplicity® Credit Card, which offers 0% for 18 months on purchases and balance transfers from date of account opening.
Remember that the 0% period is a deadline, not free money; if you still have a balance after 18 months, you will start paying interest on the remaining amount.
