It is a resort hotel but I have stayed here now twice for business purposes - each time at Cottage Double (it is really worth that extra few pennies!). Calm and relaxed atmosphere with breakfast included, and even lunch at both Coco garden or Renaissance hotel if you stay 3 nights or over. At Renaissance, there is even a private beach and onsen which is also free to use. They remembered my previous stay and provided with ample hospitality. It will be my place to stay each time when I am in Okinawa. The only thing is don't expect the shiny American style bathroom...
