Okinawa

I'm going to Okinawa for my friend's wedding with my family tomorrow.
It's two nights stay.
I'm looking forward to visiting my old friends I have not seen for a long time.
I'm  also happy because it maybe warmer than here, Kyoto.
It'll be  the first experience for my kids, so what will they feel about Okinawa?
If they'll enjoy at Okinawa, I'll suppose to go there in summer.
