What kind of tranport to take from Kunming Airport to Grand Park Hotel ?

You can take the airport shuttle bus Route 1 to Xinying Xiaoqu (Ziteng Hotel) first. Upon arrival, you are just about 5 kilometers away from your hotel, and you can take a taxi there.

Thanks :)
How about from Grand Park Hotel to Stone Forest, any good advise ?

Since no bus is available from your hotel, you are suggested to take a taxi to East Bus Station, which is about 12 km from your hotel and takes CNY30-35. Then you can take the bus to Stone Forest, and the bus is available from 7:30 to 20:10. It takes CNY25 and about 20 minutes.
