So a girlfriend of mine and I travel together. We do not share a bed. I generally take the bunk beds in cabins of this sort.

In this cabin, the bunk beds were probably about four inches short of a standard twin, likely to make room for the bathroom. Also the bunk mattress was quite hard. As were the pillows. Luckily for me I had previously been camping out so I had my camp mattress and pillows with me. That settled that problem nicely.

If you're two adults and two kids, I imagine you'll make out just fine.

And, as for the cabin, there were no other issues. Everything was very nice. The view was exceptional. The people very friendly.
