My friends and I have visited Sanya many times. The city is at the southernmost tip of Hainan Island. When visited at the right time, you can enjoy the warm sun. Some of our old drivers who often visited Sanya, would go there just to bask in the sun. Although two days is a short time, there was still time for eating, drinking and having fun. You can visit the fish market and eat all the different kinds of seafood that you want. You can even go and lay on the beach, doing absolutely nothing, and still have a good time. Everything works here.
