I'm sorry in clumsy English
I had not gone, but examined it in WEB a little
Miyako-jima Island of November is water temperature around 25 degrees centigrade
It is slightly cold and feels that periodic wind begins to blow and gets out of the sea
The jellyfishes decrease if I compare it in summer, but there is it at all
There are a lot of cheap inns in Miyako-jima Island, but cannot expect the waiting on customers in the English
It is a Japanese site, but many inns appear here

I ride the English site that I found accidentally as an example
HOTEL Hibiscus
Because the convenience to transportation is bad, Miyako-jima Island should decide the position of the inn carefully.
If it wants not to be forced an expensive taxi to unexpected expenditure
Clumsy English and little information, I'm sorry
