2 nights stay in Jiuzhaigou and Huanglong

We shall be in Chengdu in the first week of May and we want to leave Chengdu in the morning by bus, stay 2 nights in the park area and return by bus on the 3rd day. Is there a place to stay on the way rather than riding the bus for 10 hours? are there taxis from the hotel on the way to the Scenic area of JZG and Huanglong? we can stay one night on the way and one night in Huanglong.
