Renaissance Okinawa Resort

The Renaissance sits on its own beach at Yamada, where Onna begins, and calls itself a discover resort. Its signature is time with dolphins, alongside a long menu of marine activities in the green water off the beach. There are 357 rooms with ocean views. Roy's, a sushi bar and Japanese and barbecue restaurants cover dinner, and the spa runs thalassotherapy with Okinawan seawater.

Families in February can keep busy with the dolphins and the indoor pool, since the listing gives no winter dates for the outdoor one. Maeda's cape is a short ride north along Route 58. Ask the front desk about storing a bike, since there's no published policy.
