Okinawa islands help

Almost accommodation last minute on Kerama islands .. none on the beach anyway

Any part of mainland Okinawa that is super nice? Have been looking but want someone who has hopefully been! And not just from google and pictures

Want want kerama offers- beautiful water and snorkeling

Cant get to the southern islands- already flying to Okinawa

Asking for something maybe impossible but surely one beach on the mainland is amazing?

Anyone have a suggestion 🥰
