We took a bus with part of our group to the Osaka airport, where they all promptly went to the international wing, but the husband and I were flying domestically to Okinawa.
The flight was fine, the husband fit on the plane (always dicey on non-Amurrican flights, we were especially worried for an Asian domestic flight), and we started our adventures in Okinawa!
If you are an American looking for a place to stay in Naha, I recommend the Double Tree Hilton in Naha. American mattresses! (Japanese futon mattresses are fine by me, but hard on the husband.) Also the best hair dryer I had all trip. It was right across the street from the monorail. Walking distance to Kokusai Dori street. Quick taxi ride from the airport.
We got all checked in, and walked down to Kokusai Dori street for some dinner. A&W burgers. I kid you not. They are everywhere in Okinawa!
Kokusai Dori is full of (much better) restaurants and shopping. Even has a Don Quijote!
I had been working on a hat for the sister, and finished it up that night!
