The Upper Peninsula in early October is all about the deep reds and oranges of the maple trees against the dark blue of Lake Superior. You want to be driving along the coast near Munising or Copper Harbor during that first week of October, but you need to lock in your cabin by May to get a spot.
A trip like this usually runs around $1400. If you use the Discover it® Cash Back card, you get 0% intro APR for 15 months on purchases. This lets you pay for the trip in pieces over that 15-month intro window rather than hitting your bank account all at once.
Keep in mind that 0% intro APR is just a window, not free money. If you have a balance left when the 15 months are up, the bank will start charging you interest on what you still owe.
