The Casino is located on Highway 95 near Worley, Idaho. The campground has 20 amp service connections on some of the light poles in the North parking lot. There is no charge (except I assume you are “expected” to partake of some of the activities in the casino), but it’s first come, first serve. I was there at noon on a Saturday in March, and there were about 4 light poles left. I didn’t count the number of total “connections” they have, but I saw some RV’s there, with connections. If you get the light poles on the outer edge of the parking lot, you may be able to use your slideouts. If you use the light poles within the parking area, there is no room for slideouts, as cars could be on either side of you.
