That was really entertaining to follow your steps on Okinawa, especially with two little kids that is a real adventure. I bet your littles really enjoy the whole trip, starting with plane, that is really exciting for children and summer is one of the best time. My mother-in-law says "double-trouble" when she has two or sometimes three of her grandchildren at once, so it might be for you too. To keep them all the time in your sight, you never know what they have in their mind. The photographs are really beautiful, I love those on beach and playing on sand beach, at waterside if I remember my son could stay the whole day.

Shurjuji castle looks really old and beautifully decorated, I also would definitely visit it if I were you. I think the kids enjoyed the underwater world and all those fishes.

Thank you for such interesting holiday post and I wish your twins belated Happy Birthday!
