No way this gets a free hotel in Chengdu. Probably CA wouldn't cough up even on a paid business class ticket!
It is an interesting destination though. Besides the rocket center (unlikely foreigners would be welcome to visit, heh), Xichang is useful as a back door to Lugu Lake then Lijiang. Or into some rugged hiking and minority culture visits in the Muli area. Or the asbestos mine at Shimian.
