Late spring is the sweet spot for Portugal's coast. May and June bring warm sun, mild ocean breezes, and quiet cliffside paths before summer crowds arrive. You get the best views in the Algarve and Lisbon's historic streets without peak-season prices or extreme heat.
A solid two-week trip runs about $2,400 for flights, coastal stays, and train rides. Instead of paying that all at once or letting interest pile up on a standard card, we can break the total into steady monthly payments over time.
Remember that a 0% APR period is a strict deadline, not free money. If you still have a balance on the card after 15 months, the standard interest rate kicks in on whatever amount is left.
