Turning 40 deserves a real celebration, especially at a nice boutique hotel where you can actually unwind. Hitting those off-peak travel months makes the whole thing cheaper and less crowded.
Big trips have deadlines, so your timing matters. Booking the right pieces early locks in lower rates, while other details can wait until the dates get closer.
That intro window is a hard deadline, not free money. If you still have a balance left when those 15 months are up, standard interest kicks in on the remaining amount.
