Late winter is the best time to see Paris because airlines slash ticket prices just to fill empty seats, and the museums actually have breathing room. You can walk right up to the Mona Lisa instead of fighting a wall of selfie sticks, and cozying up in a small cafe on a gray afternoon feels like the real city. It is cold, sure, but you trade the summer crowds for actual space to breathe.
When you are looking at a $2600 price tag for the whole week, breaking it down helps make it feel real instead of overwhelming. We just need a clear plan so you can lock in your flights and tickets without scrambling for cash later.
Just remember that 0% intro APR for 15 months on purchases and balance transfers is a hard deadline, not free money. If you still have a balance left when those 15 months run out, the card will charge interest on what is left.
