Standing above the Sacred Valley as the morning mist clears over Machu Picchu is worth every bit of planning. May to October brings dry skies and stable trails, making it the prime season for hiking and exploring. Most travelers fly into Lima, grab a local flight to Cusco, and then head up into the Andes.
A solid trip usually runs about $2,200 total. You do not need to drop all that cash at once or pay credit card interest to make it happen if you spread the cost out smartly over time.
A 0% interest window is a payoff deadline, not free money. Once those 15 months end, any remaining balance gets hit with the card's standard variable APR, adding interest charges to whatever you still owe.
