New York City in January and February is cold, but it is also quiet, cheaper, and incredibly cozy. You get the ice rink at Rockefeller Center with fewer crowds, easier Broadway tickets, and a chance to see Central Park under a blanket of snow. It is the best time to experience the city like a local, without the suffocating summer tourist rush.
A solid weekend trip usually runs about $1800 once you factor in flights, a decent hotel, and dinners. Instead of dropping that all at once, you can stretch the cost over time. By using the Discover it® Cash Back, you can take advantage of its 0% intro APR for 15 months on purchases and balance transfers to pay off the trip slowly.
Remember that 0% interest is not free money; it is just a temporary grace period. Once those 15 months are up, the regular variable APR kicks in on any remaining balance, which will quickly make your cheap winter getaway a lot more expensive.
