Thanks for all of the advice! Thus far I have booked Hyatt Regency in Kyoto March 28-April 1, Kayotei in Kagaonsen April 1, Park Hyatt Tokyo April 5-7, Andaz 7-8.

Left to book: Kanazawa, Takayama.. open to suggestions here! Will these book up quickly too?
Will probably day trip from Kyoto to Nara
Was thinking to either day trip or book in Nikko around the Tokyo portion

I am a big monkey fan ;-) Will I regret not heading toward Nagano?

Thanks for your help!
