Arrived on 9/4 (labor day 9/5).  Was packed day we arrived, but most left the next day.  When the crowds left, most of the extras shut down for the season.

Staff was friendly and property was mostly clean.  First night felt a bit overcrowded.  They rent golf carts / gators, and there was alot of people noise the first night.

Second night was better.  Most of the crowd had left and we got to enjoy a quiter night that felt more like camping.  The pools all closed, and most of the on property food options closed for the season on labor day.

Being a KOA Resort, this place felt like it would be a great place to stay if you have kids, and/or a large rv.  There are many ammenities on property (before they close for season).  It is very close to Mount Rushmore (we drove right by it to get here), and a pretty location (especially when the crowds left)
