Changbaishan Airport Surrounding Hotels

I am planning to fly to CBS airport from Dalian. After arriving to visit the mountain from the northern slope direction, where should I stay? Songjianghe, Changbaishan or other place? I am looking for hotels or areas that are not in the middle of no where.
What are the opening and closing times of the park?
If I stay in a hotel in Songjianghe, will I be able to reach the northern slope as it is closer to western slope?
Is it hard to find transportation from the airport if we arrive around 8pm?

Many thanks in advance and a quick reply would be very appreciated as I am planning to go there this weekend
