My woman's retreat was at a military beach resort in Okinawa, called Okuma. It is just beautiful. Great place to go camping on the beach, or stay in a cabin (aircondioned) or stay in the hotel there. There is just so much to do there; water sports, hiking, walking, golfing, fishing, and what ever else they have...
I went with my church, had a blast and got refreshed... Oh how nice, even if it was just for one night.... Ahhhhh.
