Leshan -> Emeishan -> Langzhong -> Chengdu

Hi,

we're planning to go in the morning to LS, visit the Buddha and that area and then take a bus to Emeishan in the afternoon, climb it and take shelter for the night in some of the temples. On the next day we want to wake up with the sunrise and enjoy the morning with nature on the mountain and then climb down and transfer to Langzhong.

Do you think this is doable and not to intense?
Do you know about any nice transport possibilities between the the places?

We would also go from Langzhong to Chengdu, do you know if there is any night connection?

thanks for your time and help!
