We were in group of 4 traveling with local guide at Hainan, near a place called Bo Ao - checking out the small local food cafe by the river. Look ordinary & backdated house with slightly poor hygiene. When we order for simple seafood meal for 4 persons includes prawns, crabs (no lobster) plus some local veggies, failing to "negotiate" & pay off early before a meal, the bill came up to RMB1,767.00 equivalent to SGD353.00. That is more than a seafood meal at a low end 5-star hotel in Singapore. Its totally rip off...

We were pleasantly surprised when we landed at Sanya. The place and hotels are really nice and welcoming. The beaches are beautiful. Get out to the hot springs - try to avoid places with to many kids - I love them but they reduce the "chillout factor" - there are some new ones that are really nice. The food in Sanya is superb - look for places with fewer smokers and cleaner tables :)
Our friends had fun looking for pearl necklaces and things.
