Red rocks, massive canyons, and wide desert skies make a Grand Canyon and Zion road trip unforgettable. You want to aim for spring or fall to dodge brutal summer heat, but you need to lock in those park lodges up to a year in advance.
A solid week-long run through both parks usually costs about $2,400 for gas, permits, gear, and stays. Spreading that total out over time lets you secure your spots early without taking a huge chunk out of your bank account all at once.
Keep in mind that a 0% intro period is a strict repayment deadline, not free money. If you still have a balance when the 18 months end, high interest kicks in on whatever amount remains, so set up autopay for $133.33 each month to wipe it out in time.
