Thanks for all the great suggestions so far...couple questions about staying connected:

-If I bring my iPhone what is a good option that won't cost me a fortune (not going for Biz, so I can't bill this!)?

- Is it worth it to bring my MacBook? Staying at Hilton Osaka and Conrad Tokyo, but don't really feel the need to pay a lot for daily internet access. I hear free wi-fi spots are hard to come by in Japan? Do either of these Hilton properties have free wi-fi in the exec lounge?

Thanks!
