yanoda rain forest, cheap close place to sleep

there is a bus from Haikou that takes a person to yanoda and returns the following day.

where can I stay cheaply nearby?

if i stay in Sanya, I would need transportation to and from the park and I do not want to do that.

Where can I find a bed for one night that is cheap and not too far from where the haikou bus will drop me off and pick me up? I would be willing to camp for the night too, or sleep in a private home, anything. If there is something, please give me a website, phone number or email.

thank you
