I stayed in a tent cabin at Lake Alpine.  There were beds in the cabin, but the mattress wasn't that comfy.  If you're not staying at one of the regular cabins I would say to just get a campsite and stay in your own tent.  The area was really pretty.  It was a popular campground so there were a lot of people, but the way the cabins were set up it didn't feel crowded.  There was a trail that went around the whole lake that didn't have a lot of traffic, which made it nice for getting out and exploring.  The lodge had a restaurant with a full bar.  There was a small store attached to the lodge, stocked with all the things you may need.  You could rent kayaks or paddle boards there as well.  The bathroom had pay showers and flush toilets, but it wasn't really that clean.
