Transfer baggage and layover at Kunming Airport

Hi,

I will arrive with a group of friends at Changshui airport at 9pm , 26th Apr , by China Eastern airlines, and have to layover there til 5am for the next fly to Shangri-la. I have heard that China Easter airlines will offer shuttle bus and hotel room for free as a transit local flight, is that true? if not, what kind of options do we have to layover at the airport?
Thank you so much!!
