lodging on mt emei

hello - we're a family of 4 (kids are 9 and 12) and will be staying on the mountain 2 nights, 3 days in early OCTOBER. we are wondering if there are families that rent out a room or 2 of their home (guest houses) or if lodging is completely restricted to the temples? is it important to figure out where we will stay beforehand or can we decide on our lodging a few hours before we're exhausted each day? thanks!
