I am visiting Okinawa next week for 4 days. Didn't plan much yet because we prefer traveling chilled and relaxed rather than completing all the sites in hurry. Only booked snorkeling and want to get some ideas from you guys.

Please share with me if you have any suggestions! Restaurant, sites, or any tips will be appreciated.

Thank you!
