November is the ideal time to hit Taiwan. Summer humidity drops off, the rains quiet down, and wandering through Taipei's night markets or riding the high-altitude Alishan forest train is actually comfortable.
A typical trip from the US comes out to about $2600. Instead of dropping all that cash at once, you can spread the cost over time with a 0% interest offer and pay it down in predictable monthly pieces.
Remember that a 0% intro period is just a deadline, not free money. If you still have a balance when the 18 months end, interest kicks in on what is left, so set an auto-pay for $144.44 each month to wipe it out on time.
