Crete gives you the best of Greece without rushing. You get warm water at Elafonisi, old Venetian harbors in Chania, and quiet mountain villages where lunch takes two hours. Booking six months out is the sweet spot if you want a stone villa with a sea view instead of a cramped hotel room.
A trip like this typically runs about $3800 for flights, a rental car, and a solid place to stay. Dropping that much cash at once hurts, so we need a plan to spread it out over time without paying extra.
Remember that the 0% intro window is a strict deadline, not free money. If you still have a balance left when those 18 months are up, interest kicks in on whatever is left over.
