Lisbon in November is quiet, the crowds have left, and the air is crisp enough for heavy pours of red wine. You can spend your days wandering the steep, tiled streets of Alfama without bumping into a dozen tour groups every turn.
You can manage the $2800 cost by breaking it into manageable chunks. Using the Discover it® Cash Back card, you get 0% intro APR for 15 months on purchases and balance transfers to help spread out the payment.
That 15-month window is a deadline, not a gift. If you still have a balance after the 15 months, you will start paying interest on whatever is left, so treat this like a strict monthly bill.
