We stayed there last night. They have 8 full hookup sites about 1 block from the casino. About half of the sites have very nice concrete pads and the others are a little beat up (cracked, etc.). They are adjoined to an abandoned "trailer camp" that is for sale. The casino charges $5 a night plus $20 deposit returnable in the morning. The deposit covers the keys to open the water and electric hookups.
We thought the scenery would be nice since it's on the Mississippi river. Only problem was all the freight train traffic between the river and the casino. Also, the river front is quite industrial. The town only has around 900 people. After 10pm everything was very quiet. The trains didn't start up again until morning.
The casino was nice. We each got a free t-shirt for signing up and getting a player's card (free). They had the usual slots and table stuff. The restaurant was very good. There was a $7.99 lunch buffet with prime rib, clams and port loin. All the employees were very friendly and called us by our first names as we entered the casino.
