I want to travel to Dandong. How much does it cost to go to Dalu Island with a group?

To tell the truth, if you can find a place to live, you can go by yourself, otherwise there will be too many people to find a place to live. With the group is to ride together and take a boat together. Others play by themselves at the seaside, and there is nothing free and unfriendly about going to Dalu Island, because you have to go back and forth to catch the tide. I suggest going to other places by myself, because time is relatively free, but I suggest going with a group, which costs about 280 yuan. The fare from Dandong to Donggang is less than 10 yuan per person. It doesn't seem easy to get to the dock from Donggang by car. If you dare to tide, you have to take a speedboat, which is very expensive. It's cheap to go to your usual place. There are also several big hotels with unknown prices. The point is that it is really difficult to find a place to live in the peak season.
