Hello David,
Sorry to be late in answering.
Regarding our September trip to Okinawa, it appears that it is not possible to interface every leg of the trip that I am planning with my friend.
The reason for that is we are PADI licensed to scuba dive, but because you are not licenced your have to be "experiencing" diving, and because our itinerary is already fixed.
Let's drink together on the night of the fourteenth. I checked with my friernd, who said, "let's."
For airline tickets and reservations I think it is best to ask travel agents, and Mr./Ms. Lee.
We might get together for piano practises. When is the time convenient to you?
So long.
