hotel or hostel nearly huanglong or how do i get from huanglong valley to chengdu at the end of day?

Hi, here is what I know as for your questions:
1. As for the entrance to the valley, you can surely enter without joining a tour guide. I traveled there alone in Oct. of 2011.
2. At the main entrance of the valley, two direct buses are scheduled every day to Huanglong at around 07:00 and 07:30. The bus fare is around CNY45 per person.
3. Since the tourists for the journey are in a large number, I suggest you book the bus ticket in advance from the nearby bus station or a hotel. But it is too early too book now.
4. After visiting Huanglong, you can take a bus to Chuanzhusi, where there are buses back to Chengdu.
5. There are many hotels in Chengdu. I heard that the bus from Chuanzhusi may take you to Chadianzi Bus Station in the city, so you can find a hotel nearby.
6. As for the accommodation near Huanglong, I know a hotel there named Hualong Resort. It provides relatively good service.
Hope help!

thanks so much for you quick response, you have answered everything I needed to know, and made life so much easier. God bless you!
