Thank you very much for all of your helpful suggestions. ^^^ I would otherwise not be able to figure out the schedule myself. The Hyperdia site is helpful too.

The tea is part of a package @ SR Osaka which I am hoping to treat Monsieur D for his hard work. I think we will have the tea as soon as they allow us at 330. We will shove the scones and jelly down and leave the hotel at 4 for the taxi to Namba for 430 train. That should give us enough time for our 640pm flight.

Thanks again for all your tips! Can't do it without the experts from Flyertalk! Will be thinking about you guys when I sip my tea. Cheers
