Driving the Pacific Coast Highway is best done in late spring. You get bright, clear skies before the heavy summer fog sets in, and the crowds are thinner. It is the best time to see the cliffs and the ocean without fighting for a parking spot.
For a typical $2200 budget, you can manage the cost by spreading it out. The Citi Simplicity® Credit Card offers 0% for 18 months on purchases and balance transfers from date of account opening. This lets you pay for the trip over time without the extra sting of interest.
The 18-month window is a deadline, not free money. If you have a balance left over when those 18 months end, you will start paying interest on the remaining amount.
