Hi All,
Just need some advice

I have been to tokyo before but only for 4 nights. I am planning to go again sometime this year, probably late this year at this stage. This time will be for my honeymoon. Now basically this is my plan:
I will fly from SYD-HKG-SYD. I will have 1 month off. So I was thinking maybe 5 days in HKG and the rest for Japan. So leaves me around 3 weeks for Japan. Should I get a tour package from HKG to Japan and back to HKG or should I buy my own return tickets for HKG-NRT-HKG and purchase some tours in tokyo? I prefer the free and easy method while having some guided tours outside of tokyo. I wanted to visit hot springs, hokkaido, kyoto, osaka, mt fuji if time permits. Should I leave anything out of the list or are these nice places ot get a feel of japan.
Are any of those doable for 1 night or I need 2 nights for each one?
Also I will need to make it as affordable as possible

Accomodation and travel.
I would prefer to have 4-5 days in tokyo, I will be stayin gat ANA IC most probably as I had a fantastic 4 night stay before.
Hotels don't need to be 5 star, Holiday Inn type will be good enough I think. Say 3-4 stars.
Cheers,
Kenn.
