Check out the cabins they have for rent. There are loads of these accommodations in the valley. Some cabins are very simple, just electricity and beds, while others have a full bathroom. I’ve stayed in both types and I thought they were great. Just don’t expect anything super fancy and I think it should be fine. The fun thing is that when you go with a large group (I went two different times with groups from high school), you can try to get cabins near each other and it feels a little bit like being in a little village.
