Thanks to all who have replied! I am now looking at hotel reviews on Tripadvisor, etc, to begin looking at hotels. I have bookmarked the Shibuya Excel, as it sounds like it is smack in the middle of things. We will visit Disney maybe once or twice, but since the trip is about Japan rather than Disney, we will not use Disney hotels as a base. I think we have enough frequent flyer miles for most of us to fly for free, so that will help the sting of costs. My son is graduating college next May, and he majored in business/Japanese, so he wants to do this. I love to plan, so keep your comments coming! Thanks.
