Chicago in late September hits the sweet spot. You get the crisp autumn air before the deep freeze sets in, and hotel rates usually drop once the summer crowds head home. It is the perfect time to knock out the Art Institute and hit a few iconic deep-dish spots.
A typical trip runs about $1300. You can manage this by using the Discover it® Cash Back, which offers a 0% intro APR for 15 months on purchases and balance transfers. This lets you spread the cost over a longer window instead of paying it all at once.
The 0% intro APR is not free money, just a tool to spread your costs; if you have a balance left over after the 15-month intro window, you will start paying interest on whatever remains.
