Thank you so much Nancy. That's very useful info. I'm planning some more trips and would really appreciate it if you can help me plan these 3 day trips by giving me the time of departure and return available (assuming we can stay about 3-4 hours at each place) and the ticket cost for the following:
9/6/17: Chengdu Xinnanmen Station ---1.5 hrs to ---> Pingle (round-trip for same day)
9/13/17: Chengdu Xinnanmen Station --- 1.5 hrs to ---> Huanglongxi (day trip)
9/17/17: Chengdu Xinnanmen Station --1.5hrs to --->  Mt. Qingcheng (day trip)
What time would be the departure time be available for these trips:
9/14/17: Chengdu Xinnanmen Station-- 2hrs to ---> Leshan Giant Buddha
(does the bus drops you right close to the Giant Buddha itself? If not, how do we get there?
then after 2 hours, we probably want to head to Emeishan. Is it easy to find a taxi to drive us directly to the Happy Hotel in Emeishan? (the taxi estimate quoted me 53 mins and cost 79-101CNY, is it accurate as I read somewhere that smaller vehicles don't have access to the expressway and might take 4 hrs) If not, what's the best way for us to get to Emeishan Baoguo Bus station/Happy Hotel after visiting the Giant Buddha? Returning to Chengdu, what's the latest bus departure time and fare for:
On 9/16/17: Emeishan Baoguo bus station ---- 3hrs to ---> Chengdu Xinnanmen
Thank you so much in advance,
Madeleine
