First-world problems

I'm getting closer to finalizing plans to blow some frequent-flyer miles this fall. I'm down to three choices, though one city has taken a slight lead:

• Tokyo. The end of November is supposed to have the best foliage. I can also have enough hotel points for three free nights.
• Budapest. Colder than the other two top choices, but a very old friend would meet me there for a day or two. Oddly, having to connect through New York gives the trip the longest travel time of the three options.
• Madrid. Excellent opportunity to practice Spanish. Warmest weather of the three choices. Also the smallest city—which could be relaxing, or not. Also, a nerdy reason: Iberia, which operates the non-stop service from Chicago, flies an Airbus 340 on the route, which would be a pleasant change from the 777s and 767s that I usually take overseas.

What reasons am I overlooking?

I will probably book the trip Saturday.
