What will you be doing in these 2 places? The most I spent was 4 days in Osaka, and i ran out of things to do after the 3rd. Kyoto was pretty much the same deal, including Nara (full day), and completing the course at Fushimi Inari, it last me about 4 days in 2007

I just came back from a 22 days honeymoon, i visited the following cities in the 22 days

Hakata
Miyajima
Hiroshima
Kobe
Osaka
Nara
Kyoto
Hakone
Yokohama and Shink Yokohama
Tokyo (Includes these districts: Akihabara, Ueno, Asakusa, Nishi Asakusa, Harajuku, Shijuku, Ginza, Ikebukura, Omiya)
Nasu
Nikko
Kinugawa

Our trip includes a lot of train ride, it wasn't exactly "hectic", but a bit of a rush.

With 20 days, you can cover a lot more than just Osaka and Kyoto... just a thought...
