Many thanks for your advices .
a) Is 'NEX Suica package' good and cheap? I heard that 'keisei skyliner' is cheaper, is that true? Since the costs for both directions are the same, which direction is more easy and convenient for travelling and planning? How far is the osaka airport to the osaka city? is there any free shuttle bus available from Osaka and Tokyo airport?
b) Ya, you are right, i better drop some of them. Since lack of time, which of the places are highly recommended and also 'must see'.
C) No, me and my mum would prefer to have our own room with private toilet. The most important are clean and in convenient location. The price of Ryokan Tokaisou in Tokyo seems to be reasonable, but is it easy access to Shinjuku and Disneyland?
d) Can you recommend any ensuite accommodation in Osaka so that I can easily access and travel between Osaka and Kyoto, also from osaka airport. How much estimated costs of travel between Osaka and Kyoto for each day?
e) I saw a few local tour agents offer packages included transportation and accommodation. Is it worth to join? or it's cheaper if arrange myself? How about "The Shinkansen Tour" offered by 'Japanican'?
As for your question:
Osaka - sorry that I have no idea about the Starwood points? How to purchase?
Sorry if I'm asking too many questions, and I really appreciate of all your valuable information.
