Greece is better when you aren't fighting crowds for a sunset view in Oia. In May or September, the water is warm enough for a swim but the ferry tickets aren't sold out. You get the white-washed villages and the blue domes without the August heat or the cruise ship swarms.
A solid two-week trip usually runs about $5,000. Instead of waiting years to save that up, we can use the Citi Simplicity® Credit Card (Citi). It gives you 0% for 18 months on purchases and balance transfers from date of account opening to pay it off slowly.
The 0% interest period is a tool, not a gift. If you still have a balance after those 18 months, the interest kicks in at the regular rate on whatever is left.
