How much is a three-person tour from Cixi, Ningbo to Sanya, Hainan in about 3-5 days?

Travel, or suggest a self-help tour is better. The cost of traveling with a group is low, but there are generally shopping spots. Time spent in scenic spots is too limited to arrange scenic spots freely. You can't enjoy yourself because you are in a hurry to catch the scenic spot. Therefore, it is suggested that self-help tour is better, and you can arrange scenic spots freely without time constraints. The main problem of self-help tour is how to spend less money to go to good scenic spots and have fun. Free travel, three people excluding accommodation, about 3500 is enough.
