wo shi kunming ren.hahaha, maybe can help you
It is better go with the tourist agency cause you have to take his parents. you can fly to Kunming directly, staying there for couple of days, no need to find the tourist agency so hurry, in the region of Kunming, TAXI will be the best guide for you. you can visit EXPO garden, and minoirity village少数民族 cun( can not type chinese faire le cope coller), and then go with tourist group to DALI, LIJIANG, even further more you can go to MEILI, LU GU Lake, but not sure his parents'health is GOOD encough or not.
Strongly purpose LIJIANG with your LG, it is a place of soul, remember my word, and taste it yourself. I LIKE IT SO MUCH. few years ago, dream i will open a bar there, but.....hehe
Maybe you can check this link, i think c'est pas mal,am in the office right now, will come again this evening to TYPE CHINESE to give you more information, if you like please PM me
