Hainan Island... where to stay and what to see?

I'm thinking of going to Hainan Island during National Holiday. Gonna rent a car and head down.
So anyone with any thoughts about where to stay on a budget and what is there to see that you might recommend?
I've seen the webistes and done my research... now I'm looking for comments from people who have actually been there or are there!

Thanks much

Kris

Hi K...

My friend said Hainan is all about "hai",which means sea.And you have to dive.That all she said.:)
