We stayed here Memorial Day weekend, May 28 - 31. The five stars are not because it is a five star resort, but because we thought it was so great for the extremely affordable price and the thoughtful attention to detail.
When we checked in the owners were very helpful and made suggestions of things to do and told us a bit of history about the area. For the most part we didn't see them other than to wave until we checked out, which is how we like it. We saw deer right in the front yard as we were checking in. We would have enjoyed the camp fire pit out front, and the Adirondack chairs, but it was just too darn cold at night when we were there!
We stayed in Cabin 5, a two person cabin just across the entrance road from the office. I don't recommend this location during the busy season, as even with only a few people there, we could hear cars going in and out of the campground early in the morning. You could also hear some road traffic when sitting outside, but not a bit inside the cabin.
The cabin itself was clean and cozy. The owners are super friendly and have thought of everything you might need to be good guests and still be comfortable. They put out a stack of "dirty jobs" rags so you could clean up mud, wipe off the car windows, etc., without messing up the good towels. They even had a nice clean tin can by the stove, with a paper towel under, so that you had a safe place to put grease drippings! I know, that sounds weird, but I really appreciated the thought even though we never used it. We turned off the heat whenever we went out and the place heated up quickly when we turned it back on in the evening.
I really liked the location, just east of Custer, because we wanted to spend time in Custer State Park and it was one of the closest accommodations outside the park (and vastly more affordable than anything in the park!).
