Have been to this park a number of times. Bathrooms were clean. The staff is young, friendly, and always helpful. The site we stayed in was very private, the camp grounds is located in the woods. You have to sacrifice level ground for this privacy, but for me the rustic feel and privacy hugely out-weighs the 5 inch drop my site had. We did not get electricity and water this time, but have gotten it in the past. Leave at an odd time, or there will be a long line at the dump station!
No showers! I thought I read somewhere that they did, but they don't. (Not yet, the campground 'soop' said they plan on getting them.) No water hookup. We did get the electric hook up. For $1 self pay, you can get to the sewer dump and fresh water hook up on the way in, or out. They do have fresh water near the sites too, just no hook ups. I liked the park setup. Bathrooms were gross according to my wife. Park is very cool. I would stay again.
The only reason to stay at this park is probably the theme park, and the theme park is not a huge reason to come to Custer unfortunately. The sites are a long way away from the theme park. We walked, but it is a hike (esp with small children). The theme park is very well maintained. There is a small train that goes photo ops. There is a Flintstones car on a VW chassis. Kind of cool. Everything is clean there and freshly painted. Free movie theater to go and watch Flinstones cartoons. Basically you can see everything in 30-45min and there this is a playground. That is it. Not much. The campground itself is not very well maintained. The mini golf is free except you have to pay for golf balls if you need them. It is rotting and falling apart, but OK for free. The sites are packed together. We got full hook up and that is the further-est away from the park, we didn't know that. There are dump stations, so I would recommend getting something closer to the entrance and dumping later, you are not going to stay at this place for that long anyway (or you shouldn't, you'll be bored out of your mind). We are glad we stopped for a day to check it out, won't go again though. Admission to the park is $10 for adults. Our children were 2 and under, so they were free. This park is perfect for kids under 6 maybe. I saw a poor 13 year old being dragged around, clearly bored out of his mind.
Don't call it a time share, they'll let you know that they hate being called a time share, they are more like a membership. Anyway, it was a nice place except for a few things: they are rebuilding and by 6:30am every morning they had skidsters driving around moving dirt. Not a huge deal for us since we were up early to go see the sites and we also didn't really pay much. We called them up and got the $30 deal for 3 nights, then when we stopped in Wall Drug we got a flier that said we could stay there for free for three nights plus get free tickets (if you set this up with them, tell them you want the free deal that is on the fliers). We called them up and since we had planned on boon docking at a Wal-Mart asked them instead of refunding our money (which I figured they would refuse to do) if they would just give us the three free nights and another night for the $30 we had paid. They said no problem. When we got there their computers were down and we were told no way could they do that, once you get a deal you are stuck with a deal. We argued and were pains in the butt, and eventually they gave it to us. Their front office is very disorganized. The "tour" took about 2.5 hours (they said 90min, but if you have ever done time share presentations you know how that goes). Doesn't seem like a bad deal, but at this stage in our lives with two little kids we were not ready to commit $6,000 to a membership. Check it out if you are into the time share scene though, seems like a much better concept then the traditional time share. They have events scheduled every night for kids, but they canceled twice while we were there and one night was a BBQ with the owners that they charged $5 to attend (we passed on it). Great place for free, probably wouldn't pay what they want a night to stay there. We were packed in like sardines when the place started to fill up. No shade for us in the full hook up section. But again, free is free and it beat boon docking at Wal-Mart another night.
