How to get to Yalong Bay in Sanya from Haikou Airport?

Hello! Now you can't return the car in a different place for one day, otherwise you will have to hand it over to 200 yuan. You can only rent a car in Haikou and return it in Sanya for more than three days. There are still seven Ruifeng cars. Wanning is repairing the road, and now it has been repaired to Lingshui section. Don't worry, the public security in Hainan is much better, and there will be no robbery. But it is an old road with only two lanes, so pay attention to safety when driving.
