a visitor?

So Friday I get an email from T-rent explaining how his good friend from HS, Lyn, is coming to Japan and that he'd be there Saturday, the next day. Lyn is doing the Semester at Sea thing, so he'll only be in Japan for 4 days. I first talked to him tonight. Tomorrow he's staying by me and we're planning to, in Lyn's words, 'Party like Rock Stars.' When Philip came I'd say I had a very good time out, but not even close to Rock Star-like. I have high expectations for such an event. Problem: i have had zero time to plan anything and do not know places in the area to go for such an event. I decided to try a slightly different life-style in Japan, so this will be quite an experience for me as well as Lyn. All I can think about right now is all the people I've met so far and what they could bring to the table...
