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.

Do yourself a favour. Find a guide or someone who respects the great wall and get away from the crowds and experience the quiet and special character of a truely great monument. You cannot help but be moved by the idea of the labour and lives of those that worked on this collosal project over the centuries. BUT - respect it and take care when hiking.
