Itinerary check – Christmas/ New Years

Hi all! We have a trip planner from Dec. 20-Jan 4, and would love thoughts on our itinerary (keep in mine this is my 3rd time to Japan, my family’s 2nd)

Dec 20: depart LAX

Dec 21: arrive HND, check into hotel near Tokyo station

Dec 22: day trip to kawagoe for unagi

Dec 23: brother arrives on separate flight.
Explore shinjuku area and visit senso-ji

Dec 24: Tokyo disneysea

Dec 25: Shinkansen to Kanazawa

Dec 26: explore Kanazawa

Dec 27: day trip? Any suggestions?

Dec 28: depart Kanazawa for Kyoto

Dec 29: explore Kyoto

Dec 30: day trip to osaka

Dec 31: drop brother off at ITA airport, explore osaka

Jan 1: New Years. Visit temples in Kyoto

Jan 2: Nara day trip

Jan 3: open to suggestions – thinking about switching to osaka hotel if we take a flight instead of Shinkansen back to tokyo

Jan 4: flight or Shinkansen back to tokyo, leave for LAX.

Some suggestions needed:
Suggested day trips from Kanazawa?
Suggested day trips from Kyoto?
Should we take the Shinkansen or a flight back to tokyo? Our flight back to LAX isn’t until mid afternoon (3pm).

We’re big into food, so any restaurants or food destination suggestions are highly appreciated!
